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.
Live 402 challenge
Captured by the enrichment pass, not read just now. Prices can change. Always read the 402 the endpoint answers with.

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.

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.

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.
