Why vaethat API

The endpoints competitors don't advertise, because they don't have them.

Cost preview endpoint

Call /v1/estimate to know exactly what a job will cost and how big the output will be, without spending a credit or invoking a GPU.

Idempotency keys

Pass an Idempotency-Key header to retry safely. Duplicate submissions return the original job instead of double-charging.

Signed webhooks

Every callback ships with an HMAC-SHA-256 signature. Documented retry schedule (30s to 6h) plus a GET /jobs/:id fallback.

Sandbox keys

vth_test_ keys come with every API plan, never charge credits, and echo the input as output: wire up integrations before you ship.

How it works

POST /v1/enhance

Submit an image URL and a mode: standard, enhance, people_foreground or people_background. Receive a job_id immediately.

GPU processing

We run the enhancement in the mode you chose, at the size and price /v1/estimate quotes.

Signed webhook

We POST a signed payload to your webhook_url with the output URL. Poll as a fallback.

Frequently asked

Do API credits share with my UI subscription?

No. API plans are a separate billing track. Credits from a Developer / Scale / Studio plan are only spent through the API and never affect your in-app credits.

Which plans can issue live keys?

Live keys (vth_live_) need an active API plan, developer or higher. Sandbox keys (vth_test_) come with the same plans; there is no free trial.

Do I get refunded for failed jobs?

Yes. If a job fails on our side (GPU error, upstream timeout), credits are automatically refunded. You only pay for successful enhancements.

What are the rate limits?

There is no per-minute request cap. Jobs are processed in the order they arrive.

Maximum image size?

Inputs up to 50 MB; outputs up to 8000px on the long side and 64 megapixels. A larger input is refused, and a larger output is scaled down to fit.

Do I have to credit vaethat in my app?

Yes. Live API plans require a visible 'Powered by vaethat' label (text or badge) wherever enhanced images appear in your UI. A clickable link to vaethat.com is recommended but not required. Sandbox/test usage is exempt.

Every API plan comes with sandbox keys. Build against them, then switch to a live key to ship.
