## 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-bazaar-cheapest-endpoint-finder-65736215
```

Example prompt: Find me the cheapest x402 endpoints that do web search, but only show ones with at least 5 unique payers in the last 30 days so I know they're actually being used.

## When to prefer this

Use this endpoint when you need to identify the lowest-cost x402 API for a specific capability and want to avoid untested cheap listings. Prefer it over generic keyword search when your primary decision criterion is price and you want adoption-filtered results. If you need broader discovery by keyword or want to browse all endpoints regardless of cost rank, the Bazaar keyword search endpoint is more appropriate.

## Known failure modes

- No endpoints match the requested capability — returns empty list or 404
- Capability string too vague or misspelled — returns irrelevant or empty results
- min_payers threshold set too high — filters out all available endpoints
- Stale index data if daily refresh has not yet completed — may miss very new listings
- Payment of 0.005 USDC required; missing or invalid x402 payment header returns 402

## How this service works

Cost-optimised endpoint selection: name a capability (web search, token safety, enrichment) and get the x402 endpoints that provide it ranked cheapest-first in USDC per call, filtered by real adoption so untested $0.0001 listings do not masquerade as bargains. Refreshed daily from the Bazaar discovery index. `offset`/`limit` page through the full ranked list (up to 100 rows per call); `cheapest` always names the globally cheapest listing, whichever page you asked for.

## Output

An ordered list of x402 endpoints matching the requested capability, sorted ascending by USDC price per call, each entry annotated with adoption signals (e.g. unique 30-day payers) so agents can distinguish genuinely cheap, proven endpoints from cheap-but-untested listings. Refreshed daily from the Bazaar discovery index.
