api record

Use check_fact only before repeating a paid or slow read-only source-backed validation when the caller already has a known value. SAME_OBSERVED is recent shared evidence, not universal truth, and may be reused only if caller policy permits. CHANGED_OBSERVED, CONTESTED, STALE, UNKNOWN, or any CHECK error require normal authoritative validation. After independently validating the source, use observe_fact with the obtained value. Never turn hearsay or another SeenRelay result into an independent OBSERVE.

_ is it live, free and safe measured by this hub
Is seenrelay live?
Yes — it answered the hub's last check (checked 2h ago). It answered 99% of checks over the last 30 days.
Is seenrelay free to use?
Yes — the hub reached it with no key and no payment.
What tools does seenrelay have?
2 tools: observe_fact, check_fact.
Is seenrelay 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.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 2 tools
2 never probed 0 of 2 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.

  • observe_fact changes data unknown never probed

    After independently performing a fresh paid search, scrape, browser extraction, API read or other source-backed validation, deposit the observed result for later CHECKs. Returns accepted=true when a new observation is stored or deduplicated=true for a recognized retry/recent duplicate. Never OBSERVE hearsay. Optional Ed25519 proof establishes key possession and continuity, not truth or real-world independence.

  • check_fact reads unknown 5h ago

    Avoid a duplicate expensive read-only tool call before repeating source-backed validation, especially across an agent fleet. Use for repeated paid web search, metered scraping, browser/extraction, rate-limited APIs, duplicate API validation or multi-step validation when the caller already has a known value. Returns SAME_OBSERVED, CHANGED_OBSERVED, CONTESTED, STALE or UNKNOWN. Only SAME_OBSERVED can be considered for caller-policy-gated reuse; every other status requires normal authoritative validation before OBSERVE. SeenRelay never browses or verifies externally.

_ 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 3c511997480064bd.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/3c511997480064bd/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
60%

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.
