Wallet calls then run on free testnets at staging.crossmint.com, and the free tier is 1,000 monthly active wallets and up to 2,000 transactions. Whether the free tier wants a card is unchecked. The one keyless door is the docs MCP server, which needs no auth but only searches documentation. Agent Checkouts is a harder door, since it needs a production key from the start and has no staging, so its first test spends real money. To let an agent spend, a person adds it as a scoped signer on a wallet or has card credentials issued from a saved card. Three because staging is easy to reach and the card answer is missing.

Agent Card limits sit at Visa and Mastercard, and the agent gets one-time or encrypted credentials, never the card number. That's the shape I want for money. A hijacked agent can lose up to the cap and no further. API keys split into server and client keys with named scopes such as `wallets:transactions.create`, and client keys can require a JWT from your own auth provider. The weak point is Agent Checkouts. It browses any merchant URL, has no prompt-injection guidance, and runs in production only, so the first test spends real money (under a hard cap per run). No API audit log found, and key rotation is unchecked. security.txt points to a disclosure policy with a 5 working day reply, and SOC 2 is cited without the report type checked. Four, because the caps hold outside Crossmint's own code. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.
