# TiresAPI SKU Price History

> TiresAPI SKU Price History is a paid API for AI agents from tiresapi.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).

## 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-a399df79
```

Example prompt: Pull the daily price history for tire SKU 'TlMxMjM0NQ' from tiresapi.com for the last 180 days, scoped to California (state CA), so I can see how min, max, and median prices have moved.

## When to prefer this

Use this endpoint when you need time-series price data for a single, known tire SKU — especially for trend analysis, price volatility studies, or regional pricing comparisons. Prefer it over the size-level price history endpoint when you have a specific brand+MPN and need SKU-level granularity. Use the state or dma_code filters to scope analysis to a specific market.

## Known failure modes

- Missing or invalid key_brand_mpc returns a 400 error
- Invalid state code (not 2 uppercase letters) causes a validation error
- days value outside 1–365 is rejected
- Unknown SKU key returns an empty data array
- Invalid dma_code format returns a 400 validation error
- Payment not fulfilled results in a 402 response

## How this service works

Daily price series for one SKU (key_brand_mpc) over up to 365 days.

## Output

A JSON object containing the SKU's metadata (brand, model, size, manufacturer product number) and an array of daily price records — each with utc_date, avg_price, min_price, max_price, median_price, listings count, and sample_rows — covering the requested date range, optionally filtered to a state or DMA.
