Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 tiresapi-com-46f82051
```

Example prompt: Show me the latest tire inventory for size 225/65R17 within 50 miles of ZIP code 90210 — list up to 200 results with prices, store distances, and brand tiers.

## When to prefer this

Use this endpoint when you need raw, paginated inventory rows with full store-level detail (price, location, brand tier) for a given tire size, SKU, retailer, or geographic area. Prefer this over /answers/best_price_near when you need more than one result, want to compare across retailers, or need to do your own analysis. Use the summary=true mode for aggregated band/severity analysis instead of row-by-row data.

## Known failure modes

- 402 Payment Required if no valid filter param is provided and no x402 payment is sent
- Empty result set (auto-credited) if no inventory matches the filters
- 400 Bad Request if zip_code is not exactly 5 digits or state is not a 2-letter code
- 400 Bad Request if no required filter (tire_size, key_brand_mpc, retailer_key, zip_code, or state) is present
- Pagination cursor mismatch if cursor value is stale or invalid
- radius_miles exceeding 200 returns validation error

## How this service works

Latest-snapshot inventory rows (up to 200/page). Requires at least one filter (tire_size, key_brand_mpc, retailer_key, zip_code, or state); if none are on the URL, zip_code defaults to 33705 (Tampa) with radius_miles=40 so discovery probes reach a 402. For cheapest-in-radius use POST /api/v1/answers/best_price_near.

## Output

A paginated JSON object with a 'data' array of up to 200 inventory rows and a 'page' object for cursor-based pagination. Each row includes tire_size, brand, model, single_price, brand_tier (Best/Better/Good/Economy), retailer_key, store_num, city, state, zip_code, store_distance_miles, key_brand_mpc, manufacturer_product_number, last_extracted timestamp, and history_id.
