How it works

Two kinds of buyer use this service: people who want a report about their website, and AI agents that call small utilities and pay per call. Neither needs an account.

If you are a person

Reachability report — $69

  1. List up to 20 pages on your site on the order page.
  2. Pay on Stripe's hosted checkout. Card details never reach this site.
  3. Once Stripe confirms payment, every page is fetched as nine real clients — curl, node, Python urllib and requests, libwww-perl, Chrome, GPTBot, ClaudeBot and Googlebot.
  4. You get a private report page: what refused each client, the likely cause, the exact fix, and a command to reproduce it.
  5. Fix things, then re-scan up to 3 times within 30 days, free, to prove the fix worked.

If you are an agent (or build one)

Paid endpoints use x402, the HTTP 402 payment protocol. There are no API keys: the payment is the authorisation.

  1. Call a paid endpoint normally.
  2. The server answers 402 Payment Required with the price, network and receiving address.
  3. Your wallet signs a USDC transfer on Base and retries with a PAYMENT-SIGNATURE (x402 v2) or X-PAYMENT (v1) header.
  4. The payer is screened against a sanctions list, the payment is verified and settled, and the handler runs.
  5. If the call fails (any status 400 or above), settlement is cancelled and nothing is collected.

See it for yourself — this returns a real payment challenge, not an error:

curl -i -X POST https://agentic-endpoints.com/once-key -H 'Content-Type: application/json' -d '{"namespace":"demo-4f9c2b1e8d7a","action_key":"abc123"}'

Other ways to pay

Free trial

POST /credits/trial returns $0.10 of credit — about 10 calls — with no wallet, signature or account.

Prepaid credit

Buy $6.00 of credit for $5, or $32.50 for $25, then send X-Credit-Token instead of signing every call.

Ways to connect

Plain HTTP

Every route is described in /openapi.json and, in prose for models, /llms.txt.

MCP

Point any MCP client at https://agentic-endpoints.com/mcp. Listing tools is free; each call costs its route's price.
