## 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 walmart-pro-seller-badge-checker-137fcc50
```

Example prompt: Can you check if my Walmart store qualifies for the Pro Seller badge? My on-time delivery is 97.2%, valid tracking is 96.5%, cancellation rate is 1.1%, and my 90-day GMV is $52,000.

## When to prefer this

Use this endpoint when you need a deterministic, rule-based eligibility check against Walmart Pro Seller performance thresholds rather than manual lookup. Ideal for agents automating seller account health monitoring, pre-application audits, or periodic badge retention checks on Walmart Marketplace.

## Known failure modes

- Missing required query parameters (otd_pct, vtr_pct, cancel_pct, gmv_90d_usd) result in a validation error
- Non-numeric string values for percentage or GMV fields may cause parsing errors
- Values outside realistic ranges (e.g. OTD > 100%) may return unexpected results
- Service unavailability on the fly.dev host results in connection timeout

## How this service works

Check Walmart Pro Seller performance thresholds.

## Output

Returns a JSON object with: a boolean `pro_seller_eligible` indicating overall badge eligibility, an `issues` array listing any metrics that fail Walmart's Pro Seller thresholds (empty if all pass), an echo of the submitted input metrics, and an `as_of` timestamp for the check.
