# x402 Data API – Market Price Statistics by Capability

> x402 Data API – Market Price Statistics by Capability is a paid API for AI agents from tb2s28fm0h8dkq2t.68r.lambda-web.us-east-1.on.aws, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-25).

Returns price statistics (min, quartiles, median, max) for x402 APIs matching a capability query, including the median among APIs with 3+ payers and the cheapest options with their uptime.

## 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-data-api-market-price-statistics-by-capability-261327eb
```

Example prompt: What's the typical price range for x402 APIs that do web search — give me the min, median, max, and show me the cheapest ones with their uptime.

## When to prefer this

Use this endpoint when you need to benchmark or compare pricing across x402 APIs for a specific capability, understand the price distribution (not just a single price), identify affordable and reliable options, or make a cost-informed integration decision. Prefer this over individual seller endpoints when you want market-wide statistics rather than a single seller's offerings.

## Known failure modes

- No matching APIs found for the queried capability — returns empty or null matches
- Query string too long (exceeds 200 character limit) — returns validation error
- Capability query too vague — returns statistics aggregated across unrelated APIs
- Payment of 0.003 USDC not received — returns 402 Payment Required
- Lambda cold start or service unavailability — returns 5xx error

## How this service works

Price statistics (min, quartiles, median, max) of the x402 APIs matching a capability in Bazaar search, the median among APIs with 3 or more payers, and the cheapest ones with their uptime.

## Output

Returns a JSON object containing price statistics (minimum, first quartile, median, third quartile, maximum) across x402 APIs matching the queried capability, a payer-weighted median price computed from APIs with 3 or more distinct payers, and a list of the cheapest matching APIs including their uptime percentages.
