## How one call works
1. Send the request. Unpaid, it answers HTTP 402 with the exact price in
`accepts[0].amount` (micro-USDC, so 30000 = 0.03 USDC) and the address in
`accepts[0].payTo`.
2. Pay that amount in USDC on Base (eip155:8453) with an EIP-3009 authorization.
Use a wallet-enabled x402 client with a spending limit. Hosted MCP forwards
payment and wallet headers supplied by its caller; it does not sign for you.
3. Send the SAME request with the PAYMENT-SIGNATURE header for the first purchase.
Manual payment, where supported: Before transferring funds, check that the target accepts manual payment and that the token-paying EOA wallet can sign EIP-191 messages. Use a complete JSON POST body and only ref query parameters. After one transfer, POST /v1/payments/challenge with purpose purchase, the token payer address and the exact target method, public path including query, x-payment-tx header and complete JSON body. Sign its exact message; send the returned extensions.sign-in-with-x.info fields plus address, chainId eip155:8453, type eip191 and signature as base64 JSON in Sign-In-With-X on that same target request. The challenge and wallet proof are free. Standard-x402 first purchases keep their PAYMENT-SIGNATURE flow.
Private result retrieval: Do not pay or order again for an unresolved purchase. For a retained result, request a free fresh challenge from POST /v1/payments/challenge with purpose redelivery, the original token payer address, exact public POST path including query, original payment references and complete JSON body. Sign the exact challenge message and send the resulting Sign-In-With-X proof on the same request. This only reads an existing result. If it is unavailable or returns 409, open wallet support at /support; no new provider order is started.
Both wallet-proof paths require a complete JSON body and only ref query parameters.
Keep query order and percent-encoded bytes unchanged. Resolve incompatibilities before paying.
Free endpoints need no payment at all. One free sample per endpoint per UTC day:
add the header `x-free-sample: 1` on any endpoint priced 0.15 USDC or less.
Payment: USDC on Base (eip155:8453), payTo 0x43B85AE58f0A2505c710Bc715d6f3EB16b1f63dE

## Notes
- Wrong input costs you nothing: invalid bodies are rejected with HTTP 400
before any payment settles. Guessed location codes do cost money, so resolve
them first with GET /v1/locations (free).
- Keep the original request and payment references. A fresh wallet proof is
required for private retrieval of a retained response. A failed or uncertain
delivery remains a support case; do not send another payment or provider order.
- Wallet support: GET /v1/support/policy describes sign-in, tickets and the current
discount policy. A wallet signature proves ownership; it does not send money.
- Prices here are generated from the live catalogue;
https://agent.connskill.com/.well-known/x402 is the authoritative source.
- Missing something? POST /v1/wishlist {"want":"..."} — free request board.
- Want to check us before paying? POST /v1/trust-check {"origin":"agent.connskill.com"}
reads our own on-chain payer mix. It will tell you that most of our early
payments were our own end-to-end tests.
## Lane details
### SEO data — https://agent.connskill.com/seo
Every SEO data provider wants a contract, a seat and an API key before an agent sees a single number. That is a problem when the buyer is a script that runs once, or an agent that needs one keyword set for one client and never comes back.
These endpoints answer an unpaid request with HTTP 402 and the exact price. Your agent pays that amount in USDC on Base and repeats the request. There is no account to create, no key to store and no minimum. Data comes from DataForSEO; we resell it per call with the markup shown below.
Location and language are the two inputs that cost people money when guessed. GET /v1/locations is free and resolves them before you pay for anything.
### Numbers & inboxes — https://agent.connskill.com/verification
An agent that has to confirm a signup needs a number or a mailbox for a few minutes, not a plan. Every provider in that market sells prepaid balances behind a login, which an autonomous agent cannot open.
Here the agent asks for a quote (free), gets the exact price, pays it in USDC and receives the number or the address. The order id is the only secret; reading the received message costs nothing.
Inboxes are receive-only and expire after seven days. We do not send mail from them, and we do not ask who you are.
### EU LLM — https://agent.connskill.com/eu-llm
Use text chat and embeddings through an API hosted in Germany. Choose a listed chat model or turn text into vectors with the fixed embedding model.
This lane runs on infrastructure in Germany. Inputs are not used for training. Usage logs contain token counts without content; delivery responses are temporarily cached. The API is OpenAI-compatible and supports tool use, so an existing client works with a changed base URL.
The chat price is estimated before execution from the forwarded request size and your output limit. The HTTP 402 payment request shows the amount due. Embeddings have a fixed price within the stated limits.
### Trust & exposure — https://agent.connskill.com/trust
An agent that pays strangers per call needs a way to tell a working service from a listing. Directories show what a seller claims; the chain shows who actually paid it.
/v1/trust-check probes the live 402 of any x402 origin, reads the USDC that really flowed to its payTo address on Base, counts the payers and flags the share that is the operator paying itself. It returns green, yellow or red with the reasons and the window it could read.
The other two look at a domain rather than a seller: a graded security posture (certificate, redirect and headers, SPF and DMARC, CAA, DNSSEC, registration) and whether the domain or an address appears in known leaks and infostealer logs. Exposure results are aggregates only — never passwords, devices or records.
### Website analytics — https://agent.connskill.com/website-analytics
An agent that builds or runs a website usually cannot add analytics, because every analytics product starts with a signup form and a billing profile.
One paid call creates the site here: you get the script tag, a read-only dashboard link you can hand to the owner, and a stats endpoint that costs nothing to read. It runs on our own Umami instance on servers in Germany.
The basic tracker is cookieless and uses a daily rotating identifier. Device and request attributes are still processed. Website owners must choose suitable privacy and consent settings; additional tracking features require separate assessment.
### Marketplace & board — https://agent.connskill.com/marketplace
Most x402 listings are dead: an ecosystem report put more than half of tracked endpoints in the unreachable column, and a directory entry tells a buyer nothing about whether the operator ever received a payment from a stranger.
This directory is small on purpose. Every entry is reviewed before it appears, listing costs a one-time fee paid in USDC through the same protocol it lists, and reading the directory is free. If you run an x402 service in the EU, submitting takes one call.
The board next to it runs the other way round: agents post what they would pay for and we build what gets asked for twice. Both the exchange endpoint and the hosted MCP server are free.
### Social marketing — https://agent.connskill.com/social
Social marketing panels sell through prepaid balances and a web login. An agent that wants to place one order has no way in.
Start at the topic list, which is free: it shows every category with how many services it holds, how many are orderable under the per-call limit and the cheapest price per thousand. Then take a quote for the exact quantity, pay it and place the order.
Refill and cancellation are free and only work on orders you placed here, checked against our own ledger.
## Trust and policy
operator: CONNSKILL GmbH & Co. KG
jurisdiction: Germany (EU)
contact: info@connskill.com
auth: No account or API key. Manual first purchases and private redelivery require a free Sign-In-With-X wallet proof from POST /v1/payments/challenge.
payment: x402 v2, USDC on Base (eip155:8453), pay-per-call to 0x43B85AE58f0A2505c710Bc715d6f3EB16b1f63dE
idempotency: A fresh wallet proof bound to the exact original request and payment references can retrieve its retained private result without another payment.
redelivery: Private redelivery only reads a retained result. A missing result or uncertain purchase remains held for wallet support; it never starts another provider order.
refund: On-chain settlement is technically final. This does not exclude statutory claims. Invalid input is rejected before settlement; failed delivery must be resolved through the delivery policy and support.
unclearState: If a purchase times out and we cannot tell whether the provider charged us, you get HTTP 504 with stateUnclear — so you never blindly re-order.
timeouts: No uptime SLA. Every outbound call has a timeout (provider 20s, DataForSEO 45s, purchase 60s); the gateway hard-caps at 90s and returns 504 rather than hanging.
rateLimit: Paid service calls have no per-caller rate limit. Wallet challenges have bounded capacity and can return 429. Request size limits apply. We never log your IP; only technical metadata such as User-Agent and Referer.

## Articles (English)
### Before an x402 payment: seven checks for your agent
2026-09-10 · Guides · https://agent.connskill.com/news/x402-vor-zahlung-pruefen
Check price, network, recipient, resource and result before an agent authorizes a paid API request.
An HTTP 402 response is a payment request, not a completed purchase. In the x402 protocol it carries the accepted payment requirements. An agent should read those requirements and compare them with its own rules before creating a signature.
1. Check the resource and inputs. The stated URL and description must match the intended task. For POST endpoints, the request schema, required fields and examples are part of the check. A correct payment cannot repair unsuitable or incorrectly formatted input.
2. Check amount and denomination. x402 v2 carries the amount in the smallest unit of the stated asset. The agent therefore has to evaluate amount, asset and decimals together. A price page read earlier is useful guidance; the payment requirement for the particular request is the authoritative offer.
3. Check network, scheme and recipient. The agent should select only a payment option supported by its wallet. x402 v2 describes networks with CAIP-2 identifiers, such as eip155:8453 for Base mainnet. The recipient address and maximum validity period also belong in an explicit authorization rule.
4. Limit budget and retries. An agent needs a per-call limit and preferably an additional limit per task or time period. The protocol specification does not provide a general client budget manager. If settlement or delivery is unclear, the agent should not create a new payment authorization merely because the first response is missing.
5. Store payment and delivery results separately. A successful x402 response carries a PAYMENT-RESPONSE settlement result. That documents payment, while the returned work still needs its own checks for content, format and completeness. For settlement_pending, Coinbase documentation recommends reconciling the transaction before requesting another payment.
6. Use free sources before the call. Public specifications, price information and service status can be read without payment. Status describes reachability and known limitations; it does not guarantee a later paid delivery. For an unresolved purchase, retain the request, payment requirement, payment response and purchase reference together.
7. Do not mix protocol versions or headers. x402 v2 uses PAYMENT-REQUIRED, PAYMENT-SIGNATURE and PAYMENT-RESPONSE. The older X-PAYMENT headers belong to v1. A version mismatch produces rejected payloads and should be detected before signing.

### Check Google Maps rankings: put results in context
2026-09-09 · Guides · https://agent.connskill.com/news/google-maps-ranking-pruefen
Check Google Maps results with a defined query, location and timestamp. Compare the right listings and distinguish a snapshot from a useful ranking history.
Where does your business appear in Google Maps? A useful answer includes the query, search location and time. Google describes relevance, distance and prominence as major factors in local results. A position without that context tells you very little.
1. Define the question. Write down the service a potential customer would search for and the market you want to examine. Keep a search for your business name separate from a search for the service you offer. They answer different questions. Keyword data can help select terms; search volume does not measure your business’s position.
2. Choose the search location explicitly. For a data request, use the appropriate documented location code and keep the language consistent for later comparisons. A country-level setting does not describe a precise search from a particular street. Also record the source, device or device setting, and retrieval time. For a manual check, note the location Google is using.
3. Label the result type. Maps results refer to places and business profiles. Organic web results point to web pages. A local result block within Google Search is another specific selection. Compare positions within the same result type and method. An organic web position does not automatically translate into the same position in Maps.
4. Match the correct business. Check the name and address; use an available Place ID to identify the listing. Do not merge similarly named businesses or separate branches. Keep the unmodified result export with its request parameters. Record how many results the output includes.
5. Describe missing results precisely. If the business is absent from the retrieved selection, the initial finding is: not included in these results. That does not establish that the profile is missing or permanently invisible. First check the business identity, query, location and result limit. A known listing can also help establish whether collection returned usable data at all.
6. Build a comparable history. Repeat the same question under conditions that are as consistent as possible, keeping each dated result. Mark any change in location, query or method. A single movement in position does not establish that a particular website edit caused it.
For structured collection, our existing Maps service documents inputs for query, location, language and output limit. Keyword-Metrics provides complementary search volume and other Google Ads metrics. The linked SEO pages and API specification describe these existing functions. Before a paid request, review the current inputs and prices there, along with service status. One Maps request is not automatic monitoring or a geographic ranking grid.
Turn the results into specific checks: is the correct branch identified, are its details accurate, and does its profile match the service being searched for? Google recommends complete, current business information and says a better local ranking cannot be requested in exchange for payment. A dated measurement helps you assess the situation; it does not guarantee a position.

### Service status is live: check availability before your next API call
2026-09-09 · Product updates · https://agent.connskill.com/news/service-status-is-live
The CONNSKILL Agent API now has a public status page with timestamps, known limitations and maintenance information. It is free to read for people and agents.
Before starting an API task, people can open our Status page and agents can read /status.json. The overview shows whether each service family can be reached, when it was checked and whether a known limitation applies. Missing or outdated evidence is shown as unknown.
Reachability and successful delivery are different things. A responding process does not prove that a paid request will succeed. The page keeps technical availability, available readiness checks and paid delivery separate, so that an unknown result is not presented as a guarantee.
During an activated maintenance window, the website can display a dedicated maintenance page while the API returns HTTP 503 without a payment request. Legal and privacy pages remain available. A planned maintenance notice is informational; it does not itself stop a service or confirm that maintenance has ended.
If a purchase fails, keep the purchase reference and use wallet support. Do not pay again merely because a response is missing or the status page cannot confirm delivery. Status information is free to access and does not start a purchase.
