o402 0.1.5

//! OpenAI-compatible HTTP gateway, paid with x402.
//!
//! Load one TOML file, bind `server.bind`, and serve `/health`, `/ready`,
//! `/v1/pricing`, and a billed reverse proxy to an OpenAI-compatible
//! upstream (Bifrost). Chat/completions/embeddings/responses use `upto`;
//! other exported HTTP paths use `exact`. Realtime WebSocket and admin
//! paths are rejected.
//!
//! Default features are `evm` + `svm`. Production extras (`near`, `xrpl`,
//! `hedera`, `avm`, `aptos`, `keeta`, `tvm`, `stellar`, `concordium`) are
//! behind `full`. `experimental-tron` is opt-in and is **not** in `full`.
