Open workspace
Free evaluation

Start with real evaluation credits

New public workspaces receive 1,000 one-time credits for normal API requests. The NSFW daily allowance is a separate, explicitly selected path with stricter eligibility rules.

Billing and pricingCreate account
Evaluation grant

Reach a real verdict before paying

The grant is applied once, idempotently, to a normal new public workspace.

01Create a workspace

A normal public signup receives 1,000 evaluation credits automatically. No card is required.

02Create an API key

Use a workspace-owned events:write key. The secret is shown once and every request is attributed to that workspace.

03Send standard requests

Basic text, image, and video requests use the evaluation balance. At current defaults, 1,000 credits cover about 1,000 basic-text, 500 image-only, or 166 video-only requests; mixed requests settle from their combined cost.

04Review real usage

Requests, incidents, and credit debits appear in the same workspace console before you decide whether to buy credits.

NSFW daily allowance

Do not treat it as a general free tier

Only requests that explicitly select and satisfy the NSFW policy shape can use these daily buckets.

Rule
Set options.billing.contentClass to nsfw explicitly; general is the default and consumes credits.
Rule
Use the no-custom-rules text path. Custom rules, transcripts, suggestion schemas, and forced suggestion keys are not eligible.
Rule
Stay within the fixed daily text, image, and video buckets shown by the billing endpoint.
Rule
Eligible allowance usage costs zero credits; overflow returns to standard credit billing.
After evaluation

Move to paid usage deliberately

Keep credit exhaustion, rate limiting, and authentication errors distinct in your integration.

Check GET /v1/billing/credits before high-volume testing.
Buy usage credits from the workspace billing page when the evaluation balance is low.
Keep the NSFW content class limited to requests that satisfy its documented policy shape.
Treat HTTP 402 as exhausted credits and HTTP 429 as a rate ceiling; they are not authentication failures.
