## Call it

MCP tool call:

```json
{
  "name": "ads_get_optimization_rule_eligibility",
  "arguments": {
    "store": "myStore-US",
    "countryCode": "<countryCode>",
    "body": {}
  }
}
```

Tool API (early access — contact us):

```bash
curl -X POST https://api.sellersheetai.com/api/v1/tools/ads_get_optimization_rule_eligibility \
  -H "Authorization: Bearer $SELLERSHEET_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"store":"myStore-US","countryCode":"<countryCode>","body":{}}'
```

## Arguments

| Name | Type | Required | Description |
|---|---|---|---|
| `store` | string | yes | the store ref `<store>-<CC>` (name-country, e.g. 'myStore-US') — one of get_user_context's store_refs, verbatim. |
| `countryCode` | string | yes | the Ads profile's 2-letter country code (e.g. 'US'). |
| `body` | object | yes | {campaignIds: [...] (max 100), requirePerformanceMetrics (default true — false also lists eligible campaigns with no roas yet; read performanceMetricsExists)}. |

## Result

- Amazon's payload in data.result.

## Gotchas

- Eligibility needs the campaign running >=10 DAYS, >=10 CONVERSIONS in the last 30 days, and the marketplace's minimum daily budget. Use the returned roas as the create threshold rather than inventing one — it is derived from this campaign's own history.
- Response keys are lowerCamelCase, not the PascalCase Amazon's guide shows: campaignOptimizationRecommendations[{campaignId, performanceMetrics: {roas}}]. Per-campaign failures (e.g. LOW_BUDGET, NO_CONVERSIONS — one campaign can produce several at once) land in data.failed; an empty recommendations list with errors present means NOT eligible, whatever the HTTP status says.
