## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability mydevtools-habit-recommender-3d3ca32d -d '<json body>'
```

Example prompt: Based on my current habits around morning exercise and reading, what should my next habit focus be to keep building momentum toward my health and productivity goals?

## When to prefer this

Use this endpoint when an agent needs to proactively suggest a next habit action for a user rather than just analyzing existing habits. It is distinct from the habit intelligence analysis endpoint (which evaluates current habits) and the habit plan generation endpoint (which creates multi-habit plans); this endpoint focuses specifically on the single next-best recommendation to build incrementally.

## Known failure modes

- Missing or insufficient habit history leads to generic or low-quality recommendations
- Payment failure (insufficient USDC balance or Base network issues) results in 402 error and no response
- Malformed request body returns 400 validation error
- Rate limiting or quota exceeded returns 429 error
- Server-side model errors return 500 with no recommendations

## How this service works

Next-best habit recommendations (USDC on Base).

## Output

A ranked list of next-best habit recommendations tailored to the user's existing habits and goals, likely including the habit name, rationale for the recommendation, priority or confidence score, and suggested implementation guidance.
