Agronomist API

The API and SDK let organisations build DeepLeaf infrastructure into their own services. OpenAI-compatible: set model to agronomist, send a stable farmer id. Same id, same chat.

Quick start

chat.shcurl

curl https://<host>/v1/chat/completions \
  -H "Authorization: Bearer $DEEPLEAF_API_KEY" \
  -H "X-Farmer-Id: your-farmer-12345" \
  -H "Content-Type: application/json" \
  -d '{"model": "agronomist",
       "messages": [{"role": "user", "content": "my tomato leaves have brown spots"}]}'

What the run looks like: the thinking fold and each tool call

You

my tomato leaves have brown spots

Brown rings with a yellow halo, lower canopy first. Field is day 41, 18 mm of rain in three days.

Consistent with early blight. Need registered products before naming any.

Input: {"hours": 72}
Output: 18 mm rain over 3 days. Dry 06:00 to 12:00 tomorrow, wind 5 to 8 km/h.

06:12

Likely early blight (Alternaria solani). Remove the lowest leaves today and spray tomorrow 06:00 to 10:00 with a product on the national register.

What you get

Stable farmer id: Send X-Farmer-Id or the user field. Same id, same farmer, same fields, same memory.
SDKs: React SDK for embedding, Python SDK for servers.
Embed tokens: Short-lived tokens for browsers. API keys never reach a browser.
WhatsApp relay: Keep your own number and bot; relay messages to Agronomist.
Voice calls: POST /v1/calls starts a real-time call for a farmer.
Webhooks: Field briefings and events, signed with HMAC (X-Agronomist-Signature) and carrying an idempotency key.
Versioned docs: Open /v1/openapi.json; Deprecation and Sunset headers before any meaning change.
Playground: Try requests against a sandbox farmer before writing code.

SDKs

The React SDK embeds the Agronomist chat and voice in your app. The Python SDK wraps this API for servers and WhatsApp bots, with the farmer id as a first-class argument. Both are shared with partners ahead of their public npm and PyPI release.

Security

Keys are scoped to an organisation and stay on your servers. Image URLs are not fetched by the API; send images inline. Report issues to trust@deepleaf.org.
