# datastand.dev Provider Vetting

> datastand.dev Provider Vetting is a paid API for AI agents from datastand.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Returns reputation and pricing intelligence for an x402 Bazaar provider domain: resource count, 30-day call volume, best-adopted endpoint, and min/median/max USDC price range.

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 datastand-dev-provider-vetting-350ca891
```

Example prompt: Before I integrate it, can you vet the x402 provider at api.example.com — tell me how many resources they list, their 30-day call volume, their best-adopted endpoint, and their USDC price range?

## When to prefer this

Use this endpoint when you need a quick, single-call due-diligence snapshot of an x402 provider before integrating it — specifically when you want pricing range, adoption metrics, and resource count in one response without manually querying each endpoint. Prefer it over general Bazaar search when you already know the domain and want provider-level aggregates rather than individual resource listings.

## Known failure modes

- Domain not found in Bazaar index — returns empty or 404-equivalent if the hostname has never been listed
- Domain with zero call volume — profile returned but volume metrics are zero
- Invalid domain format — returns validation error if the hostname is malformed
- Payment failure — x402 payment of $0.005 USDC not completed, request rejected before data is returned

## How this service works

Vet an x402 seller before integrating: how many resources the domain lists, its total 30-day call volume, its best-adopted endpoint, and its price range (min/median/max USDC per call), plus its most-used endpoints. Answers 'is this provider real and what do they charge' in one paid call. `offset`/`limit` page through the domain's full endpoint list (up to 100 rows per call) — the largest sellers list several hundred.

## Output

Returns a profile object for the queried domain including: total number of listed resources, aggregate 30-day call volume, best-adopted (most-used) endpoint name, USDC price statistics (min/median/max per call), and a list of the domain's most-used endpoints.
