EXOCHAIN DAG DB API DTO wire contracts
Documentation

ExoChain DAG DB API DTOs.

exo-dag-db-api owns these wire shapes. exo-api::dagdb re-exports them as the stable compatibility path for gateway, node, SDK, and external callers.

Every consumer-facing REST response DTO carries a stable schema_version string constant so a non-Rust integrator can detect the wire-contract version directly from a response body. The constants below are the single source of truth; the checked-in machine contract under docs/dagdb/api/ and the fixture round-trip tests are asserted against them.
