MCP server for AI agent payments. An agent in Cursor, Claude Code, Claude Desktop, Codex, or any MCP host can call paid APIs (search, scraping, contact data, public records, compute, media, research) from one balance, with a spend ceiling it states on every call, and no vendor keys anywhere in its environment. Billed only on success (x402 USDC on Base, Stripe MPP, or Tempo); a refused or failed call costs nothing.

First paid call: `consult` returns a priced plan; `use({ service, action, params, maxcostcents })` runs one line of it. If the quoted price is above `maxcostcents`, the call is refused before it reaches the provider and the reason comes back:

Runnable examples: `examples/pay-for-an-api` (one call allowed, one refused), `examples/cursor`, `examples/claude`. Guides: give an agent a budget, Cursor setup, Claude setup, what is an AI agent wallet.
