CrewAI recipe: a two-agent crew that buys from an x402 pay-per-call rail — real USDC micropayments, real on-chain receipts — via Steward MCP. Steward x402 Recipe for CrewAI A CrewAI agent that **buys from an x402 pay-per-call rail** — real micropayments, real receipts. The agent connects to $1 (v0.2.1, 19 tools) over MCP stdio, browses the paid catalog for free, then purchases one weather API call for Austin, TX — **$0.01 USDC on Base**, signed by your own wallet, verified before signing.

steward_purchase_instructions → gets the live 402 quote (price, USDC contract, payee wallet)Wrong payee, wrong price, over cap? Refused. No silent spending, ever.
Spend guardrails (enforced server-side, before any signature):
STEWARD_MAX_SPEND_USDC=0.05 — hard ceiling per single callSTEWARD_MAX_SPEND_DAY_USDC=5.00 — hard ceiling per rolling 24hpip install -r requirements.txt
You need two keys:
| Key | For | Required |
|---|---|---|
| OPENAI_API_KEY (or ANTHROPIC_API_KEY, etc.) | CrewAI's LLM | Yes — CrewAI needs a model |
| STEWARD_PAYER_KEY | Your Base wallet private key (0x...), funded with a few USDC | Yes — the MCP server will not start without it (v0.2.1) |
Your key never leaves your machine. It is passed as an environment variable to the local MCP subprocess only — never logged, stored, or transmitted.
STEWARD_PAYER_KEY=0x... OPENAI_API_KEY=sk-... python steward_crewai_recipe.py
The crew runs the free discovery first (catalog browse), then the $0.01 paid
weather purchase. Spend ceilings (STEWARD_MAX_SPEND_USDC=0.05,
STEWARD_MAX_SPEND_DAY_USDC=5.00) are enforced server-side before any signature.
