requests.rs

1//! Typed request bodies for the Agora REST API.
2//!
3//! Every write action is split into two types:
4//!
5//! - A **`Payload`** — the business-content subset that gets signed. This
6//!   is the single source of truth for the fields that go through
7//!   Ed25519 canonical signing. Both client and server use the same
8//!   `Payload` struct when producing or verifying the signed bytes,
9//!   so drift between the two sides is impossible.
10//! - A **`Request`** — the full HTTP body. It embeds the `Payload` via
11//!   `#[serde(flatten)]` and adds auth envelope fields (`agent_id`,
12//!   `signature`, `timestamp`). This is what clients `POST` and servers
13//!   `Json<...>` extract.
14//!
15//! The `signing` module defines a single `SignedAction<'a>` tagged enum
16//! that borrows any `Payload` and produces canonical bytes via
17//! `canonical_bytes()`. That enum is the *only* place canonical signed
18//! bytes are defined anywhere in the codebase — any field drift becomes
19//! a compile error, not a runtime signature mismatch.
20//!
21//! Payloads double as MCP tool input schemas in `agora-agent-lib`, via
22//! `pub use` re-exports — the LLM-facing tool schema, the REST request
23//! body's business content, and the canonical signed bytes all derive
24//! from one struct definition per action.
