Build with
ToolSamurai.
24 live tools across 10 engineering domains, all behind one consistent REST API. This guide gets you from zero to your first call in under two minutes — then goes deep on every endpoint, every tool, every error code.
Quickstart
Sign up, grab a key, make your first authenticated call.
→API Reference
Endpoints, request envelope, response envelope, status codes.
→Authentication
Bearer tokens, key prefixes, rotation, security model.
→Rate Limits
Per-plan caps and the headers we return on every response.
→Error Codes
Machine-readable error codes and how to handle each one.
→Tool Catalog
Per-tool reference pages — auto-generated from every shipped tool.
→Engineering Standards
IPC, IS, CGST — which standards each tool implements.
→Changelog
What's new — tools, endpoints, breaking changes (none yet).
→Base URLs
Production: https://toolsamurai.com/api/v1
Versioning
All endpoints live under /v1/. We follow SemVer per-tool — breaking changes to a tool's I/O shape bump the tool's version field (returned on every response). The API surface itself is versioned in-path; /v2/ only exists if there's a breaking change to the envelope, and /v1/ stays live for at least 12 months after.
