ycallr-core

High-performance YAML-based API caller. API profiles are defined in YAML, optionally compiled to Protobuf for ahead-of-time execution, and invoked through a shared HTTP preparation layer and native or WASM clients.

What this repository contains

Component	Role
YAML parser	Strict ingest validation and install-time parsing
Protobuf compiler	YAML to .pb via proto/api.proto
Call engine	Templates, env resolution, auth, body, response messages
HTTP client	reqwest execution of prepared requests
FFI	C ABI (ycallr.h) for CLI and other language bindings
WASM	wasm-bindgen bindings with fetch HTTP
