## Verdicts

**Skyfire API + MCP.** Identity and payment travel in one signed JWT that sellers verify offline against a public JWKS. No x402 or MPP; both buyer and seller must be on Skyfire.

**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

### Skyfire API + MCP

1. Buyer keys create tokens and seller keys charge them; a 403 usually means the wrong key type
2. Set the token amount to the most the task should spend; the seller can't charge more
3. Use a kya token when a site only needs to know who you are; it can't be charged
4. Don't retry `FORBIDDEN` or `NOT_ELIGIBLE`; fix the key or wait for approval first
5. Rehearse against mcp-sandbox.skyfire.xyz before using mcp.skyfire.xyz

### 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
