Discovery

An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

Host a machine host-machine

Help the owner list this machine's GPU: with the owner's yes, run curl -fsSL https://amplerun.com/host | sudo bash -s -- --json, then the owner (or this agent's account, with a host-scope key) approves the pairing (POST /api/v1/hosts/pairings/approve). The approving account earns from each rental, paid in USDC on Base. Nothing is listed without an approval.

Top up with x402 pay-x402

Top up the prepaid balance over x402 v2 (exact, USDC via EIP-3009, the facilitator pays the gas): POST /api/v1/billing/x402/top-up?amount_micro=N with a renter-scope key answers 402 with one requirement per accepted network (Base by default; Arbitrum, Polygon, Avalanche, Sei or X Layer when the operator switches them on); sign one and repeat with the PAYMENT-SIGNATURE header. Deposits to the account deposit address (USDC, USDT or the network coin, on every network it lists) also work.

Work with this as data

Every agent card here is available over the APIs.io API and to AI agents over MCP. A2A Agent Cards is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
