Crypto Microdata for Agents

OHLCV candlesticks (klines) for any major USDT pair with indicators precomputed, so your trading agent skips the math: symbol=BTC|ETH|SOL|BNB|XRP|DOGE|ADA|AVAX|LINK|SUI|... (or BTCUSDT), interval=1m|5m|15m|1h|4h|1d (default 1h), limit=10-500 (default 100). Returns candles [{t,o,h,l,c,v}] oldest->newest plus last close, change_pct over the window, EMA20, EMA50, RSI14, ATR14 (abs + pct), trend up|down|range, and a pullback zone EMA20 +/- 0.75*ATR (in_zone true/false).

Provider

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.

Recent payments · which agents last used it

Every indexed settlement paid to this service’s wallet, newest first. The index does not record which endpoint a payment was for, so if this wallet serves more than one endpoint, the rows include payments for the others. Paged up to the newest 5,000; the full history is on the merchant page.

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. 31 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Show the prompt
Using Roundhouse, look up the x402 service Crypto Microdata for Agents 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%20Microdata%20for%20Agents'
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://kr-x402-mvp.kgy5612.workers.dev/crypto/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.
