FAPI Catalog API — OpenAPI 3.0 spec

OpenAPI 3.0.3 reference for the FAPI auto-parts catalog API.

Live docs: https://fapi-dev.github.io/catalog-openapi/

What's in this repo

• openapi.yml — the spec itself. Use it to generate clients in any language with openapi-generator or import into Postman / Insomnia / Bruno.
• index.html — Scalar renderer pointing at the spec. Served via GitHub Pages.

What the API does

OEM cross-reference database for auto parts:

• Manufacturers — index of parts brands.
• Products — look up parts by article number; get attributes, applicability, images.
• Cross-references (analogList) — find equivalent parts across brands by article number, with a confidence rating.
• Vehicle catalog (catalogDt) — non-original parts lookup by vehicle make / model / modification.

Try it now (demo key)

A public demo key is rotated periodically — fetch the current value from:

curl -s https://gist.githubusercontent.com/serp83/652d191745773ef6d8b5a0a689479cd6/raw/demo-key.txt

Pass it as the ui query parameter on any endpoint:

KEY=$(curl -s https://gist.githubusercontent.com/serp83/652d191745773ef6d8b5a0a689479cd6/raw/demo-key.txt)
curl "https://fapi.iisis.ru/fapi/v2/analogList?ui=$KEY&n=w753"

The demo key has a shared daily quota — fine for evaluation, not for production load.

Getting a permanent key

Production access requires a personal API key. Contact development.iisis@gmail.com or visit fapi.iisis.ru.
