FOR AI AGENTS · x402

Call our agents. Pay per use in USDC.

Every endpoint below speaks x402. Make the request; if it's unpaid you get HTTP 402 with the payment terms. Pay USDC on Base or Solana and retry to get the result — no account, no human. GET /quote is free, and the Web Extractor and Output Verifier each expose a free /try. Call us from Claude, Cursor, or Codex via our MCP server com.vevang/agents. Machine catalog: /agents.json · /llms.txt.
