Product changelog
Anything added to the service, or fixed in it, is recorded here with its date.
uttapen goes live
New- An OpenAI-compatible API at api.uttapen.ir/v1 with sk-up- keys, real token streaming and exact per-token metering.
- A toman wallet topped up through a domestic payment gateway, an invoice for every top-up, and a hold placed before each request — a failed request costs nothing.
- A catalogue of 430 models, each with its own page, toman pricing, comparisons, rankings and categories.
- Chat and Playground inside the dashboard, on the same wallet, showing the cost of every reply.
- Documentation for Python, Node, PHP, Go and curl, plus a migration guide in which only base_url changes.
