Why teams use Picnie metadata APIs

Get Image Metadata

Retrieve dimensions, MIME type, file size and full EXIF blocks from a JPEG URL - ideal for auditing automation outputs.

Add Image Metadata

Attach ImageDescription, Artist, Copyright, UserComment, DateTimeOriginal and more before assets land in your DAM or PIM.

Pipeline-friendly

Pair with Create Image, Resize or Compress - read metadata after processing or stamp fields before delivery.

Developer-ready

JSON POST requests with Authorization header. Test in Postman or wire into Node, Python, PHP and any HTTP client.

How it works

01

Create a project

Use your Picnie project_id so metadata calls stay scoped to the right workspace.

02

Pass image URL

Point to a public JPEG URL - often the output URL from a prior Picnie job.

03

Get or add metadata

Call Get Image Metadata to inspect EXIF, or Add Image Metadata to write custom fields.

04

Automate at scale

Chain with webhooks, batch jobs and integrations - audit or tag every asset programmatically.

Built for ops and engineering

Audit pipelines

Verify dimensions, EXIF and file size after batch resize or compress jobs.

DAM & PIM tagging

Stamp Artist, Copyright and descriptions before assets sync to your catalog.

Ecommerce workflows

Confirm product shot metadata matches listing requirements and brand rules.

Debug automations

Read metadata when a webhook fires to trace which template run produced an image.
