api record

17 read-only research skills, plus every decision receipt in the ledger as a resource under nota://receipt/. Every skill result is RYO's public envelope: status, data_mode, as_of, availability per source and warnings. A value that could not be fetched stays null, never zero.

  • verdict_track_record reads open 16h ago

    How RYO's own deep_analysis plans have fared: locked daily for 25 majors and settled on OKX hourly candles (stop or +1R target first, 24 h or 72 h). Returns counts by verdict and by confluence state, plans whose verdict leans against their own direction, and the latest locked verdict. Omit the symbol for all tokens.

    Macro liquidity from DefiLlama (no key): 7-day and 30-day change of the total USD stablecoin supply, and of DeFi TVL on the token's own chain (ETH, SOL, BNB, AVAX and other L1/L2 tokens). Each leg reports its own as_of and availability; a token without a chain of its own gets no TVL rather than a borrowed one.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id f132ee7a03abfa29.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/f132ee7a03abfa29/claim. Over MCP: the claim_endpoint tool.

_ how we knowoff the mcp door
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
