inker API

The inker API runs the same models as the studio from your own code. You pay with the coins on your account: no subscription and no separate billing.

Base URL

Every endpoint lives under /v1 on the API host. Requests and responses are JSON with camelCase fields.

https://api.inker.si/v1

How it works

Create an API key on your account page and keep it on your server.
Pick a model from GET /v1/models: each one lists its parameters and a starting price.
Quote the exact request to see what it costs in coins.
Submit it with the quote, so you are never charged more than you saw.
Get the result by polling the generation or by receiving a webhook, then download the files.

Pricing

Every generation costs exactly the quoted coins. Failed generations are refunded in full, and partial results are charged only for the outputs delivered. Buy coins on the pricing page.

Versioning

/v1 only changes in ways that keep your code working: new endpoints, new optional fields, new error codes and new enum values. Ignore fields you do not know. A breaking change would ship as /v2.
