Crypto OHLCV candles
OHLCV candles for one crypto pair from Coinbase Exchange in one GET: time, open, high, low, close and volume, newest first, with the source URL and fetch time. curl: GET /candles?pair=BTC-USD&granularity=3600&limit=24 (granularity 60|300|900|3600|21600|86400 seconds, default 3600; limit 1-300, default 24; pair defaults to BTC-USD). Response: {"pair":"BTC-USD","granularity_seconds":3600,"count":24,"candles":[{"unix":1792670400,"time":"2026-10-22T12:00:00.000Z","open":81656.69,"high":81816.21,"low":81605.44,"close":81746.7,"volume":95.50529109}],"source":{"name":"Coinbase Exchange","http_status":200,"latency_ms":210}}. The exchange is read once after payment; a pair it does not list is a 502 and is not charged. 0.005 USDC, no account, no key, one GET, one delivery. A purchase is two calls by design: this first call returns 402 with the price and the payment terms, and you then repeat the same request with the PAYMENT-SIGNATURE header to receive the 200 delivery.
The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

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
No per-endpoint history for this service yet, so this is payments indexed to its PROVIDER's wallet over 30 days. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service Crypto OHLCV candles 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=Crypto%20OHLCV%20candles' 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://x402-catalog-history.ai-business-surface.workers.dev/candles, 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.
