_ is it live, free and safe measured by this hub
Is yieldagentx402 live?
Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
Is yieldagentx402 free to use?
Partly — some of its tools are open, others need a key or payment.
What tools does yieldagentx402 have?
19 tools: yax_delegate_to_agent, yax_submit_approval, yax_control_workflow, yax_run_secure_workflow, yax_process_x402_payment, yax_score_leads, yax_build_email_sequence, yax_monitor_churn_risk, ….
Is yieldagentx402 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 also stands behind 1 other origin: the chain figures are the gateway's, not this listing's alone. How it is counted.

_ what it can do 19 tools
1 open7 auth-required 11 never probed 8 of 19 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.

  • yax_get_capabilities reads open 2h ago

    Returns every tool available on this server, what each one does, and when to use it. Call this first when connecting to understand the platform.

    mcp-tool

    {
  "type": "object",
  "properties": {}
}
    arguments 4 lines
  • yax_verify_receipt reads auth-required 10h ago

    Projects stored receipt verification evidence. verified is true only when the stored payload HMAC was cryptographically checked and a provider GET readback matched the uploaded artifact; this call does not perform a fresh provider lookup.

    arguments 4 lines
  • yax_check_policy reads auth-required 20h ago

  • yax_get_receipt reads auth-required 10h ago

  • yax_get_attestation reads auth-required 20h ago

  "properties": {}
}
    arguments 4 lines
  • yax_audit_compliance reads auth-required 2h ago

    Audits recent agent activity against policy rules and flags violations. Returns compliant vs flagged counts and report evidence; any storage CID is an anchor reference until provider readback/content match is separately verified.

_ 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 9bbe1f0b04183195.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/9bbe1f0b04183195/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/9bbe1f0b04183195/badge.svg)](https://brick.blue/agent/9bbe1f0b04183195?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 know
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.
