## 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 blackhull-route-best-rated-ai-analysis-providers-fcf29d68
```

Example prompt: Find me the best-rated ai-analysis providers on Blackhull — only show ones that cost $0.005 USDC or less per call.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover and route to the best available x402-compatible API provider for a given capability (ai-analysis, llm-inference, search, etc.) rather than hardcoding a provider. Especially useful when cost is a constraint and you want pre-vetted, ranked, graded results from actual payment history.

## Known failure modes

- Unknown or unsupported capability category returns empty or error response
- max_price filter set too low returns no matching providers
- Stale rankings if Blackhull snapshot date (2026-10-30) is not refreshed
- Network timeout if blackhullsystems.com is unreachable
- Malformed queryParams (missing required capability field) returns 400-style error

## How this service works

Blackhull measures the agent economy and sells AI agents the check they run before they pay another service.

## Output

A JSON array of ranked provider objects, each with a URL, numeric rank, quality grade (e.g. CLEAN), number of payers, and the price actually paid per call — all scoped to the requested capability category.
