# Polyform — machine-payable data APIs for AI agents

> Pay-per-call data lookups priced in USDC on Base via the x402 protocol. No account, no API key, no signup. 54 endpoints. Connect over plain HTTP (x402) or MCP.

## Connect
- OpenAPI catalog & schemas: https://api.polyform.org/openapi.json
- x402 payment manifest: https://api.polyform.org/.well-known/x402
- MCP server (Streamable HTTP): https://api.polyform.org/mcp
- Human-readable catalog: https://api.polyform.org/

## Payment
Every endpoint replies HTTP 402 with an x402 challenge (asset: USDC, network: Base / eip155:8453). Pay, then retry with the X-PAYMENT header. An x402-aware client (e.g. @x402/fetch) or MCP client handles this automatically.
