api record

Recta is a preflight for AI agents that move stablecoins (and BTC) between blockchains. Before a transfer, the agent asks Recta; Recta reads every route it knows at the same chain state (Across, CCTP, Stargate, USDT0 and others) and returns the cheapest one it can prove, against the route the agent would have used anyway. Recta charges exactly 5 % of the saving it verifies on chain after the agent executes its route. No saving, no charge. No prepayment and no credit: the agent signs, with each decision, a Permit2 authorization capped at `max_fee_authorization`, and Recta's collection pulls…

_ is it live, free and safe measured by this hub
Is recta live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is recta free to use?
Yes — the hub reached it with no key and no payment.
What tools does recta have?
5 tools: recta_prepare_signed_request, recta_send_signed_request, recta_status, recta_service_descriptor, recta_about.
Is recta safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

    Recta is a preflight for AI agents that move stablecoins (and BTC) between blockchains. Before a transfer, the agent asks Recta; Recta reads every route it knows at the same chain state (Across, CCTP, Stargate, USDT0 and others) and returns the cheapest one it can prove, against the route the agent would have used anyway. Recta charges exactly 5 % of the saving it verifies on chain after the agent executes its route. No saving, no charge. No prepayment and no credit: the agent signs, with each decision, a Permit2 authorization capped at `max_fee_authorization`, and Recta's collection pulls only the verified 5 % (never more than the cap) in USDC on Base; the payer's ledger shows whether each fee has been collected yet (`charged`). The evaluation itself is free. Returns the full guide (llms.txt).

  • recta_prepare_signed_request unknown never probed

    Computes the exact message the agent's EVM wallet must sign (EIP-191 personal_sign) for one Recta request, and the headers to send. Holds no key and calls nothing. Then call recta_send_signed_request with the same method, path, idempotency_key, body and issued_at, plus the signature. Start with POST /v1/golden-corridor/commercial-evaluations (body: see recta_service_descriptor; its "sender" must be the signing address).

  • recta_send_signed_request unknown never probed

    Sends a request signed by the agent's own wallet to a Recta route and returns its HTTP status and JSON body. An evaluation is free; executing a decision's route creates a fee of 5 % of the verified saving, capped by the permit the agent signs.

_ try it 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 6d4ad57e46ff1232.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/6d4ad57e46ff1232/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
90%

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.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
