Verdicts

Paid

Paid suits a builder who wants usage metering, credits and invoicing behind one API, with restricted and customer-bound keys, OAuth on the MCP server and a free plan that needs no card. No status page, SLA figure, API changelog or rate-limit numbers were found, both advertised OpenAPI links returned 404, and card payments need the builder's own Stripe account.

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

Paid

  1. Call https://api.agentpaid.io/api/v2 with Authorization: Bearer <key>. A person creates the first key at app.paid.ai. No programmatic signup was found
  2. Give every signal a stable idempotencyKey and resend the same key on retry. Signals without one are not deduplicated
  3. Send at most 500 signals a request. A 429 rejects the whole batch, so wait for Retry-After and resend it all
  4. Read the code field on a 429. CONCURRENCY_LIMIT_EXCEEDED carries no Retry-After and clears when an analytics query finishes
  5. Install the Python SDK as paid-python, the name in its README and pyproject.toml. The quickstart's pip install paid names a package we could not check

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
