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
