Vaultfire Docs
Build on Vaultfire
Agent-native trust infrastructure with 75 paid x402 endpoints on Base mainnet (29 also accept Solana payments). Every endpoint is self-describing: price, signature spec, ABI, error catalog, and related endpoints — all in the 402 body.
Quickstart
/quickstartFive-minute tour. Discover endpoints, read on-chain trust data, and preview a payable action — with curl, no wallet.
Interactive Playground
/playgroundLive x402 endpoint browser. Filter by category, copy framework-specific snippets, try GETs in your browser.
