Registry code: 7588e23d83d8de82

api record

Paid tools wrapping official real-world APIs and crypto pre-trade data, billed per call via the x402 protocol (USDC on Base mainnet). Each tool's description states its price. With a funded Base wallet configured, calls return live data automatically; otherwise they return the exact payment terms so a wallet can complete payment.

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 10 tools
10 never probed 0 of 10 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.

  • crypto_token_dossier reads unknown never probed

    Full degen token dossier in one call: safety score + honeypot/tax + detailed TOP HOLDERS and concentration + liquidity/FDV/volume/pool-age + contract control (owner, creator, mintable, open-source) + an AI red-flag narrative. Deep due-diligence report on a token before aping — the premium tier above a plain safety check. EVM chains and Solana. Price: $0.10 per call (x402 payment, USDC on Base mainnet).

    Token safety check before buying — is this token a honeypot or a rug pull?

  • crypto_pre_trade_verdict reads unknown never probed

    One-call GO/CAUTION/NO-GO pre-trade verdict for AI trading agents: fuses token safety (honeypot, rug, tax, holders), counterparty wallet sanctions screening (OFAC/mixer) and cross-exchange market signal into a single decision with a signed, offline-verifiable receipt. Should I buy this token now? Replaces three separate calls (token-safety + wallet-screen + signal) with one fused GO/NO-GO verdict. EVM chains and Solana.

  • agent_rank_check reads unknown 15h ago

    Quick check of where an x402 seller ranks RIGHT NOW by keyword-relevance in the CDP Bazaar discovery (not the raw settled-volume rank the free explorers show): best rank + per-category-keyword rank in one cheap call, plus a pointer to the full /agent/visibility-audit when the rank slips.

  • agent_visibility_audit reads unknown never probed

    Audit how discoverable an x402 agent/seller is across the agent registries (CDP Bazaar, 402index): keyword-RELEVANCE rank per category (not raw settled-volume rank), a metadata-quality score of your advertised endpoints (schema, output.example, tags, llm_usage_prompt), settle activity, a top-3 benchmark, prioritized fixes, and a DELTA vs a signed snapshot you carry back. Why am I not being found and how do I climb? GEO/AEO discovery audit for x402 sellers, Ed25519-signed. Price: $1.00 per call (x402 payment, USDC on Base mainnet).

_ 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 7588e23d83d8de82.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/7588e23d83d8de82/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 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.
