Projects

Process a project

Fetches all pending images for the project, auto-detects HDR bracket sets from EXIF metadata, groups them, and enqueues all jobs in a single call.

Project must be in pending status. Returns 409 if already processing or completed.

Once this call succeeds, the project moves to processing status — no further uploads are accepted and this endpoint cannot be called again for the same project.

HDR detection: Images captured within bracketWindowSeconds of each other with an EV spread ≥ 0.5 stops are automatically grouped as HDR bracket sets. No client-side grouping is needed — upload all images flat and let the API handle it.

Payment: Charged once per project.

PAYG plans (essential / ultimate): charged at the plan rate from your pricing tier.
Monthly plans: deducts one listing from your quota; if exhausted, the overage rate is charged.
Second call on the same project (after adding more images): free — project is already paid.

Authorizations

Authorization

string

header

required

API key with fl_ prefix, issued from the Fotolabs dashboard

Path Parameters

projectId

string<uuid>

required

Body

application/json

templateId

enum<string>

default:original

AI enhancement style. Overrides the project-level default.

Available options:

original,

twilight,

virtual-stage

autoLevel

boolean

default:true

Automatically correct horizon tilt using Hough line detection.

lensCorrection

boolean

Override lens distortion correction. Omit to use automatic detection (recommended). false skips correction; true forces it.

changeRequestNote

string

Free-text instruction passed to the AI model for all images in this batch.

Example:

"Brighten the foreground and add a warm sunset tone"

bracketWindowSeconds

number

default:2

Time window in seconds used to group HDR bracket exposures.

Required range: 0.5 <= x <= 30

Response

All jobs enqueued. Project is now in processing status. Poll each jobId via GET /v1/images/{imageId}.
