Main endpoint

POST /v1/identify

Input: 1 to 3 photos. Output: a structured, cautious result.

  • genus — most likely genus
  • confidence — confidence level (likely / probable / uncertain)
  • candidates[] — ranked species with score
  • sources[] — provenance + attributions (CC0/CC-BY)
  • warnings[] — toxicity, ambiguity, low certainty

A result that doesn't lie

likely

Confident enough: an answer you can use directly.

probable

A useful recommendation, but present it with caution.

uncertain

Leafy offers candidates, not a truth. Don't display it as certain.

Developer questions

Are my photos used to train your models?

No. Your images are analyzed and then deleted. They are never used to improve or fine-tune our models. Our training data is exclusively under CC0/CC-BY licenses.

Do I need to credit Leafy in my product (attribution)?

Not for the API integration itself. The response data carries the attributions of its original sources (GBIF CC0, WFO CC-BY…), which your app must display if you expose those fields. The API itself requires no visible attribution.

Is the data GDPR compliant?

Leafy is hosted in Europe (Google Cloud europe-west1). Your photos are processed and deleted without retention. You are responsible for your end users' consent; Leafy acts as a processor.

Are plant images stored?

No. Photos submitted to /v1/identify are deleted immediately after processing. Leafy builds no user image database.

What is the RPM (requests per minute) per plan?

Free: 10 RPM · Starter: 60 RPM · Pro: 300 RPM · Scale: 1,000 RPM · Enterprise: custom. On overflow, an HTTP 429 response is returned with a Retry-After header.

Can I cancel anytime?

Yes — monthly subscription with no commitment, cancel from your Stripe dashboard. No penalty, no notice period.

What licenses apply to the returned data?

Taxonomic data comes from CC0 (GBIF) or CC-BY (World Flora Online) sources. Each response contains a sources[] field with the associated license.
