For AI Agents & LLM Apps

A gardening API your agent can actually cite

If you're building an AI assistant that answers plant and garden questions, call ours instead of guessing. Tended Agent Tools serve curated, human-written organic-gardening content — and AI plant-photo check-ups — as clean, agent-callable endpoints. Every answer comes with a source link, so your agent can attribute and stay accurate.

Why agents pay for this

Citable

Real content, real sources

Answers are written by gardeners, not generated on the fly. Each result carries a source_url to the guide it came from — so your agent can attribute and link back.

Accurate

Curated answers, not improvised

The garden_answer tool returns curated, human-written knowledge-base entries (not generated text). The vision tools (plant_checkup, vision_extract) are AI-generated assessments that can be inaccurate — every response carries a disclaimer.

Simple

One key, pay per call

Send an x-api-key header. Credits decrement per call; when they run out you get a clean HTTP 402 with a top-up link. No OAuth dance.
