api record

Multi-chain, multi-protocol crypto payment verification agent. Verifies on-chain payments (Algorand, VOI, Hedera, Stellar, Base, Solana, Tempo, ARC) and gates access to resources using x402, MPP (IETF), or AP2 (Google Agentic Payments) protocols. Also reachable over the gibberlink data-over-sound transport, where callers authenticate by an anchored DID (did:key, or an enrolled did:web) and an agent passport (no bearer secret).

_ is it live, free and safe measured by this hub
Is AlgoVoi Payment Agent live?
Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
Is AlgoVoi Payment Agent free to use?
Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
What tools does AlgoVoi Payment Agent have?
5 tools: Create Hosted Checkout, Verify On-Chain Payment, Check Payment Status, Post Twitter Checkout, Agent Trust Bench.
Is AlgoVoi Payment Agent 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 it can do 5 tools
5 auth-required 5 of 5 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.

  • create-checkout changes data auth-required never probed

    Create a hosted payment link for a given amount. Returns a checkout URL and token that an end-user can open to complete payment. Input: amount (major fiat units, e.g. 9.99), currency (ISO 4217, e.g. GBP), label (description), preferred_network (optional), redirect_url (optional). Supported networks: algorand_mainnet, voi_mainnet, hedera_mainnet, stellar_mainnet, base_mainnet, solana_mainnet, tempo_mainnet, arc_mainnet.

  • verify-payment reads auth-required never probed

    Verify that a blockchain transaction satisfies the payment requirements for a gated resource. Supports x402, MPP, and AP2 protocols on Algorand, VOI, Hedera, Stellar, Base, Solana, Tempo, and ARC networks. Returns verified=true and an access_token JWT on success.

  • check-status reads auth-required never probed

    Poll the payment status of a checkout link. Input: token (the URL slug from create-checkout, e.g. 'uW9MJN-abc123' — NOT the UUID id field). Returns status: active | paid | expired | cancelled.

    paymentstatuspolling

  • post-twitter-checkout sends messages auth-required never probed

    Create a hosted checkout link and post it as a reply to a tweet (or as a new tweet) using the tenant's connected X bot credentials. Input: amount (major fiat units), currency (ISO 4217), tweet_id (optional — reply target), label (optional), preferred_network (optional). Returns checkout_url, token, and tweet_id of the posted reply.

  • agent-trust-bench reads auth-required never probed

    Research environment measuring autonomous AI agent payment decisions under x402. 35 profiles spanning benign, adversarial, multi-turn, and budget-enforcement scenarios. Agents can probe profiles via GET /{profile_id}, refuse via POST /refused/{profile_id}, and declare pre-authorisation via POST /authorised-declaration. Available as an MCP server (bench_mcp_server.py, stdio transport) and via Bazaar discovery at /discovery/resources. Max transaction: $1.00 USDC. No auth required. Research disclosure at /disclosure-policy.

_ 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 agent card — 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 03c2d737b36f2ba5.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/03c2d737b36f2ba5/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
95%

How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.

spec deviations
0

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

_ record

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.
