Use Case

A documented, tested REST API — generated, not scaffolded

Describe your domain and Multos generates the full API: typed endpoints, validation, database migrations, OpenAPI docs, and integration tests. Deploy it anywhere in minutes.

One shot, first generation, built in under five minutes. No manual design pass.

What you get in the first generation

  • Typed endpoints with request validation and consistent error envelopes
  • Database schema with migrations for PostgreSQL, MySQL, or MongoDB
  • OpenAPI specification with interactive documentation generated from code
  • Authentication with API keys, JWT, or OAuth2 — your choice
  • Rate limiting and pagination built into the generated handlers
  • Integration test suite covering every endpoint's happy and error paths

Try it with a prompt like this

Build a REST API for a bike-share system: stations, bikes, docks, rides, and pricing. JWT auth for operators, API-key auth for partners, rate limiting, PostgreSQL with migrations, OpenAPI docs, and integration tests for every endpoint.

Paste this into Multos and you will have a working version in minutes.

Common Questions

Which frameworks does it generate for?

Your pick: Node (Express, Fastify, tRPC), Python (FastAPI, Django), Go, or Rust. Multos has dedicated skills for each stack and generates idiomatic code, not a lowest-common-denominator approximation.

Does it handle database migrations properly?

Yes. Schema changes are generated as versioned migration files with up and down paths — never raw SQL dumped into a startup script. You keep full migration history in your repo.

Can I add endpoints after generation?

Absolutely — and this is where Multos differs from scaffolding tools. Describe the new endpoint in chat and it is added with the same validation, tests, and documentation standards as the original set.

How is the API documented?

An OpenAPI spec is generated from the actual route definitions, so documentation cannot drift from code. It ships with an interactive docs page your consumers can test against.
