Server instructions

Mart402: pay-per-call extraction APIs for AI agents (x402, USDC on Base; no account, no API key). Free tools work immediately. Paid tools called without x_payment return the exact payment requirements instead of charging you. Typical workflow: check an unfamiliar x402 seller for free (search_x402_services, operator_history), pay it, then verify what it returned (verify_invoice, document_pipeline; free samples via get_sample). Docs: https://mart402.com/agents.md
