## 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 fitpulse-exercise-form-technique-lookup-a2fa4176
```

Example prompt: Can you look up the correct form for a Romanian deadlift — I want to know the target muscles, how to set up, the step-by-step execution, and what common mistakes to avoid?

## When to prefer this

Use this endpoint when a user needs detailed, structured exercise technique guidance for a named movement — including muscles worked, setup, execution steps, form cues, and progressions. Prefer this over a general fitness plan builder when the user is focused on a single exercise rather than a full program. Not appropriate for medical or rehabilitation advice.

## Known failure modes

- Exercise name not recognized or too vague — returns empty or error response
- Ambiguous exercise name (e.g. 'curl') may return generic or default variation
- Rate limit or payment failure (x402) — agent must handle 402 payment required before retrying
- Network timeout if the service is under load

## How this service works

Exercise how-to / proper form / muscles worked by exercise: look up correct technique for any movement. Returns target muscles, setup, step-by-step execution, common form mistakes, and easier/harder variations. Fitness-info for fitness and coaching agents, not medical advice.

## Output

Returns a structured breakdown of the queried exercise including: primary and secondary muscles worked, equipment setup instructions, numbered step-by-step execution cues, a list of common form errors to avoid, and at least one easier and one harder progression/variation of the movement.
