"hint": "This call costs $0.04 USDC, paid per request with USDC on Base, Solana, Polygon or Arbitrum mainnet via x402. No account, no API key. Easiest: use an x402 client (JavaScript: @x402/fetch + @x402/evm, Python: pip install x402) with a wallet holding USDC on Base; it handles the 402 automatically. Manual: sign an EIP-3009 TransferWithAuthorization for the requirements in accepts[0] (v1) or in the PAYMENT-REQUIRED response header (v2) and retry with the X-PAYMENT (v1) or PAYMENT-SIGNATURE (v2) header.",

Hand this page to an agent
Copy the prompt and paste it into Claude, an MCP client or your own agent — it will vet this service and call it over the free read API. No key, no account.
GET api.roundhouseai.io/v0/endpoints
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 22 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service agentsvc.io and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=agentsvc.io' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://agentsvc.io/api/v1/proxy/tts, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
