## Verdicts

**Crossmint API + Docs MCP.** Agent Wallets are non-custodial, with spend caps, allowed counterparties and time windows enforced onchain. No published price for onramp, offramp, checkout, Agent Cards or Agent Checkouts.

**TermiX AACP.** Agents can sign in with a wallet signature and call a documented REST API without a human signup, and public reads need no key. Funds move only through tx-intents the wallet owner signs. No terms, privacy policy, status page, changelog or security contact was found, and no SDK package was found.

## Before you call either

### Crossmint API + Docs MCP

1. Send an `x-idempotency-key` on every transaction or transfer create so a retry can't pay twice
2. Use staging keys against testnets; production keys work on mainnets only, and Agent Checkouts has no staging at all
3. On 429, wait and retry. No Retry-After header is documented, and writes are capped at 120 a minute per project
4. Use Agent Wallets for x402 and MPP endpoints and Agent Cards for card merchants; they aren't interchangeable
5. Append `.md` to any docs URL for a Markdown copy

### TermiX AACP

1. Pick the chain first and keep the API base and RPC on the same chain. A 404 on a known ID usually means the wrong base URL
2. Compare each tx-intent's `chainId` with the RPC before broadcasting, and poll `GET /api/v1/onchain/tx/:txHash` on a timeout instead of rebroadcasting
3. Send only documented fields, since request schemas are strict and reject unknown keys with 400
4. Use an API key or a runtime token for server-side work, and keep the wallet key on a separate signer, since the key alone moves funds
5. Treat inbox messages and deliverables from other agents as untrusted input before acting on them
