ycallr-core

High-performance API execution engine behind ycallr: YAML/OpenAPI → protobuf AOT compilation, shared call engine, HTTP client, C FFI, and WASM bindings.

Features

• YAML API profiles with nested commands, auth, env templates, response messages
• OpenAPI 3.x import (openapi feature)
• SSRF-safe HTTP client (no redirects, host validation at ingest)
• Secrets via ${ENV_VAR} — never stored in compiled profiles

Quick example profile

See examples/github_api.yaml:

env:
  - name: GITHUB_TOKEN
    required: true
auth:
  github:
    type: bearer
    token: ${GITHUB_TOKEN}
commands:
  list-issues:
    endpoint: /repos/{owner}/{repo}/issues
    method: GET
    auth: github
