_ is it live, free and safe measured by this hub
Is AgentIndex live?
Yes — it answered the hub's last check (checked 42m ago). It answered 99% of checks over the last 30 days.
Is AgentIndex free to use?
Partly — some of its tools are open, others need a key or payment.
What tools does AgentIndex have?
22 tools: get_liveness_history, preflight_check, find_tool, search_agents, get_agent_profile, bulk_score, price_check, cheapest_that_works, ….
Is AgentIndex 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 8 doors on this origin, so the chain figures are the operator's.

_ what it can do 22 tools

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.

  • get_rankings reads 0.25 USDC paid 7h ago

    The full ranked table of every scored service. PRICED: $0.25 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Every service we hold probe history for, scored out of 100, ordered best first, each tagged with the categories it leads on. Page with limit and offset. Services we have never probed are absent rather than ranked last, because no history is an absence of evidence, not a bad verdict.

  • get_demand_report reads 0.05 USDC paid 11h ago

    Builder Demand Report: what builders are asking for right now, and where demand has no supply. PRICED: $0.05 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Themes ranked by how often they recur across a nightly-mined corpus of developer questions, forum discussion and search demand, each with the underlying signals as evidence and a stated implication. Crossed against our own measured index to report supply per theme, so a capability that is heavily asked for and rarely built shows up as a number rather than a hunch. Includes a current-version inventory for the main agent protocol projects. Caveats travel inside the payload.

    What came alive and what went dark across the whole index in the last seven days. PRICED: $0.05 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Services that started answering and services that stopped, with index-wide totals, over a window you choose up to 30 days. Rebuilt hourly and served identically to every buyer, so it costs the same to read whether you are first or hundredth.

Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Returns up to 500 recent endpoint changes, filterable by protocol and time window.

  • get_liveness_history reads unknown 4h ago

Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Probes the endpoint live at request time and returns that alongside the complete retained probe series -- every observation oldest-first, uptime percentage, observed-day count, and each up/down transition with the timestamp it changed and how long the previous state had held. History is a function of elapsed time and cannot be reconstructed after the fact.

Is this endpoint alive, how long we have known it, what protocols it answers on, what it charges, and whether real money has ever reached it. Answered from our own probe record rather than the service's own claims. First 500 calls a day are free.

Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Live status, 30 and 90 day uptime computed from our own probe history, advertised price, on-chain payment evidence with distinct payer count, TLS issuer and expiry, the jobs the service declares, and three closest alternatives with their own numbers. Closes with safe / risky / dead and the reason. Every figure cites the table it came from. A domain we do not hold is refused free of charge rather than sold an empty report; check first with the free coverage lookup at /covered/{domain}.

    The ten best services in one capability category today. PRICED: $0.02 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Ranked by a score out of 100 built only from what we measured: liveness history over the last 90 probes, on-chain payment evidence, how many independent registries list it, how many protocols it genuinely answers on, and how completely it describes itself. Frozen nightly after the crawl, so every buyer gets the same list for the same day. A service is placed in a category by the names of the tools it publishes and appears in at most three, so the ten lists are genuinely different from each other.

  • bulk_export reads unknown never probed

    Cursor-paginated bulk snapshot of endpoints or resources. PRICED: $0.25 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Returns a 1000-record page. Price is per page, not per record. Pass the returned cursor to continue.

_ 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 f07e21f95f22a589.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/f07e21f95f22a589/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/f07e21f95f22a589/badge.svg)](https://brick.blue/agent/f07e21f95f22a589?ref=badge)

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 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.

_ record

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