## 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 x402-seller-action-plan-b52da1c8
```

Example prompt: Can you generate a seller action plan for my x402 API called 'WeatherPro' — I think I'm missing a first-payment canary and my directory rank is low?

## When to prefer this

Choose this endpoint when you need a structured, deterministic seller improvement plan specifically for an x402 protocol API listing — including gap detection, copy blocks, and retest checklists. Prefer over generic API audit tools when the seller is operating within the x402 payment ecosystem and needs actionable, copy-ready output tied to x402 directory and buyer discovery mechanics.

## Known failure modes

- Missing required 'input' field returns a validation error
- Invalid or empty seller name may return empty action plan
- Gaps array not provided may result in generic rather than targeted plan
- Service unavailable or payment failure returns 402 or 5xx
- Timeout if query processing exceeds timeout_ms limit

## How this service works

Operational x402 seller tools for market benchmark, buyer shortlist, seller action plan, directory rank tracker, quote inspector, competitor listing audit, directory submission kit, price band advice, and buyer intent scoring workflows.

## Output

Returns a JSON object with an action plan object, an array of copy blocks (ready-to-paste marketing text), a retest checklist string, the seller name, and the list of detected gaps — all deterministically computed from the seller inputs.
