Chain-agnostic agent payments.
No account required.
Agents that speak different chains negotiate a shared settlement lane and pay from their own wallet. Eleven mainnet chains, five settlement models, and extensible. Run it hosted pay-as-you-go, hosted multi-tenant, or self-hosted.
Chain-agnostic agent payment negotiation
Speak the chain vocabulary you already use, CAIP-2 ids or plain names, and negotiate a shared settlement lane. An agent posts the chains and protocols it supports; the rail returns the lanes you have in common and a recommended pick. Two agents that speak different chains converge on one, paid from your own wallet and keys, with no AlgoVoi account and nothing minted. It is agnostic and extensible across the lanes it supports today, and read-only, so discovery is free and the payment only happens once both sides agree.
# an agent tells the rail which chains + protocols it speaks

-d '{"chains":["eip155:8453","solana","hedera:mainnet"],
"protocols":["x402","a2a"]}'

}AlgoVoi Pay:
pay per call, verify offline
A payment rail built for autonomous agents. No account, no API key, pay a few cents of USDC per call and get a signed receipt anyone can verify offline. Two doors: the tenant gateway is trust through governance; AlgoVoi Pay is trust through proof.
# Discover + pay any AlgoVoi Pay endpoint, no account $ curl https://pay.algovoi.co.uk/.well-known/agent-card.json # -> A2A agent card (did:web:pay.algovoi.co.uk) $ curl -X POST https://pay.algovoi.co.uk/pay/v1/verify/receipt # -> HTTP 402 + x402 accepts[] (Algorand / Base / Monad / Polygon / Arbitrum / OP / Solana / Stellar / Hedera / Voi / Tempo) # pay USDC welded to the challenge token, then present it: $ curl -H "X-PAYMENT: <base64>" ... # -> 200 + Ed25519 receipt (verify offline via /.well-known/jwks.json)
Build agents that pay and prove it
Read the docs, point your agent at the rail, and settle in USDC with a receipt you can verify offline. No relationship required.
