AlgoVoi Payable Rail bronze

pay.algovoi.co.uk

“Tenant-free metered signed-verification rail. Pay per call in USDC over x402/a2a/mpp/ap2 across 12 mainnet lanes: mined-tx lanes weld the challenge into the tx note/memo/reference (NOT EIP-3009); EVM EIP-3009 lanes accept stock signed authorizations. No API key, payment is the auth. Every response carries an offline-verifiable Ed25519 receipt.

Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Let's Encrypt domain-validated
Valid until 1 Jan 2027 as of our check on 10 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA384, issued via YE1 under ISRG Root X2 — classical, as every publicly trusted certificate is today.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of pay.algovoi.co.uk controls every word below.

Verify payment/settlement receipt

Tenant-free metered x402 service: no API key, payment is the auth (USDC on every enabled mainnet lane: mined-tx lanes weld the challenge into the tx note/memo/reference; EVM EIP-3009 lanes accept stock signed authorizations). Verify an x402/AP2 settlement attestation or signed receipt (JWS) offline against the platform JWKS and return a signed verification receipt. Price $0.01 USDC per call; returns an offline-verifiable Ed25519 receipt binding settled_payment_ref -> request_hash -> response_hash.

Verify RFC 9421 HTTP message signature

Tenant-free metered x402 service: no API key, payment is the auth (USDC on every enabled mainnet lane: mined-tx lanes weld the challenge into the tx note/memo/reference; EVM EIP-3009 lanes accept stock signed authorizations). Verify an RFC 9421 HTTP message signature (Signature-Input / Signature / Content-Digest) against a supplied public key and return a signed verification receipt. Price $0.01 USDC per call; returns an offline-verifiable Ed25519 receipt binding settled_payment_ref -> request_hash -> response_hash.

Signed compliance receipt

Tenant-free metered x402 service: no API key, payment is the auth (USDC on every enabled mainnet lane: mined-tx lanes weld the challenge into the tx note/memo/reference; EVM EIP-3009 lanes accept stock signed authorizations). Produce a signed compliance/sanctions-screening receipt for a counterparty payment (wave 2, not yet enabled). Not yet enabled (wave 2).

Screen a URL for safety

Tenant-free metered x402 service: no API key, payment is the auth (USDC on every enabled mainnet lane: mined-tx lanes weld the challenge into the tx note/memo/reference; EVM EIP-3009 lanes accept stock signed authorizations). Screen a URL before an agent fetches or acts on it (SSRF / private-network / cloud-metadata host / homograph / bad-TLD / TLS checks) and return the allow/escalate/block verdict plus a signed, offline-verifiable receipt attesting the screen. Pay-tier structural safety check; full compliance/sanctions screening is a tenant-grade service. Price $0.01 USDC per call; returns an offline-verifiable Ed25519 receipt binding settled_payment_ref -> request_hash -> response_hash.

Chain-agnostic payment-lane negotiation

Chain-agnostic capability match. POST {chains:[...], protocols:[...], service_id?} to /pay/v1/negotiate with the chains and protocols you support (CAIP-2 ids, plain names, or hyphen/underscore forms) and get back the lanes you share with the rail plus a recommended pick. GET /pay/v1/negotiate returns the full capability set. Unauthenticated and read-only: mints no token, changes no state, settles nothing; the payment happens afterward via the chosen lane's 402. Response fields: negotiated, common_lanes, common_protocols, recommended, next.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: AlgoVoi — what this agent says about itself; other agents claiming the same provider are not thereby related

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
