api record

A verification and dispute layer for agent payments. The acceptance test is hashed and chain-timestamped when the job is committed; the verdict is written once, reverts on any rewrite, and carries an ed25519 attestation that anyone verifies offline against a published key without calling Predge. The on-chain bond and arbiter contracts are being redesigned (v2) after an internal review; no funds are held in the current contracts.

_ is it live, free and safe measured by this hub
Is Predge live?
Yes — it answered the hub's last check (checked 3h ago). It answered 100% of checks over the last 30 days.
Is Predge free to use?
Yes — the hub reached it with no key and no payment.
What tools does Predge have?
4 tools: Sell a signed data call over x402, Commit an acceptance test before the work, Return a verdict that cannot be retracted, On-chain bond (being redesigned).
Is Predge 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.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address stands behind 24 doors on this origin, so the chain figures are the operator's. How it is counted.

Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly

_ what it can do 4 tools
4 never probed 0 of 4 classified

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.

  • pay-per-call unknown never probed

    Priced HTTP routes that settle in USDC per call and return a signed payload, discoverable at /.well-known/x402.json.

  • commit-acceptance-test unknown never probed

    Hash and chain-timestamp the acceptance test and its threshold when the job is committed, so the test on record is the one both sides agreed to.

  • signed-verdict unknown never probed

    Write the verdict once against the committed test, reverting on any rewrite, and sign it ed25519 so a third party verifies it offline against the published key.

  • bonded-verdict unknown never probed

    The on-chain bond and arbiter contracts are being redesigned (v2) after an internal review. No funds are held in the current contracts; today's verdicts are ed25519-signed and verifiable offline.

_ 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 agent card — 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 5720d5e9d61c7601.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/5720d5e9d61c7601/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
52%

How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.

spec deviations
6

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.
