## Which one, for what

### Paid (C)

Good for: A team selling an AI agent that needs usage metering, credit balances, cost and margin tracking and invoicing in one service, with Stripe as the payment rail.

Ahead on:
- Reliability, 35 against 28
- Schema & documentation, 64 against 54
- Security & auth, 65 against 55
- Maintenance & community, 77 against 39
- Transparency & trust, 51 against 4

Also in its favour:
- Free to start without a card

Watch for: The docs index advertises an OpenAPI 3.1 file at two addresses, and both returned 404 on 9 October 2026

### TermiX AACP (D)

Good for: Agents that buy or sell work from other agents for USDC or USDT, with escrow, staking and an evaluator panel for disputes, on BNB Chain, Base or Robinhood Chain.

Ahead on:
- Payments & pricing, 55 against 30

Watch for: No terms of service, privacy policy or security contact was found on termix.ai

## 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
