Agent402 Wiki

Agent402 is a live node in the machine-to-machine economy: 1,000+ pay-per-call web tools for AI agents over HTTP. No signup, no API key, no account — an agent calls an endpoint, gets quoted over HTTP 402, settles in USDC on Base via the x402 protocol (or pays with CPU proof-of-work on the eligible tools), retries, and gets the result. The payment is the identity.

The one-line pitch per audience

• An agent, mid-task: every capability here needs only what you already hold — a wallet or a CPU. GET https://agent402.tools/llms.txt and go.
• An agent developer: one x402-wrapped fetch (or one MCP server) buys browser rendering, live search, PDFs, durable memory, and ~1,000 utilities at $0.001–$0.02/call, deterministic, no LLM in the serving path.
• A skeptic: the whole server is open source, every endpoint is re-tested against its own documented example before every deploy, and revenue settles on-chain to a public wallet — verify on Basescan.
