Real-time fact-checking and misinformation detection agent. Catches AI hallucinations, verifies claims, detects outdated information. You have access to VERITY — a specialist real-time fact-checking and data freshness agent. Also used by A2A agent orchestrators to verify agent claims, credentials, and capability assertions before hiring via protocols like Swarmwage or MoltGig.
Use VERITY tools to verify claims, URLs, and content against live web sources before trusting or publishing them.

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.

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.
batch_verify paid never probed
Input: claims array (up to 10 strings). Output: array of VerityResult objects. Use for content audits and fact-check pipelines.
claim_verify paid never probed
Input: claim or URL (string). Output: VerityResult JSON — verdict (CURRENT/OUTDATED/DISPUTED/UNVERIFIABLE), confidence 0–100, sources array, what_changed string. Verifies against live web via Tavily.
persistent_memory paid never probed
Remembers domains monitored, topics checked, and verification history across all sessions. Pass a consistent caller_id to activate.
deep_check paid never probed
Input: claim (string). Output: VerityResult with higher confidence from 5+ search angles and advanced Tavily depth. Use for high-stakes verification.
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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id3bf8ebaddf07e2c5.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/3bf8ebaddf07e2c5/claim.

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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
