Free Peru RUC API

What it includes
- 350 credits per month. Each
GET /ruc/{id}lookup consumes 1 credit. - The same SUNAT reduced registry data as the paid plans.
- No lock-in: stop using it whenever you want.
What its limit is
The Free plan has no overage. When its cycle credits run out, the API returns 429 until the next one starts. If you need to keep querying, move to a paid plan: there, extra lookups cost S/0.00015 per extra credit and the API keeps working.
