## 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-bazaar-search-f8ff1d72
```

Example prompt: Search the x402 Bazaar for paid APIs that can do image captioning — show me what's available, including their prices in USDC and which network they're on.

## When to prefer this

Use this endpoint when an AI agent needs to dynamically discover a paid API capability at runtime — especially when the required capability is not hardcoded and must be found from the x402 Bazaar ecosystem. Prefer this over manual API directories when you need pricing, payment address, and network metadata in one call, or when you want to find Coinbase CDP-curated or community-listed x402-compatible services programmatically.

## Known failure modes

- No results found if the query is too specific or niche — try broader terms
- Network filter typo returns empty results — ensure network name matches exactly (e.g. 'base-mainnet')
- Rate limiting or payment failure if the $0.01 USDC fee cannot be settled
- Stale listings if indexed APIs have changed their pricing or gone offline since last crawl
- Ambiguous queries may return loosely related APIs that don't match the intended capability

## How this service works

Search the x402 Bazaar (Coinbase CDP discovery index) for paid APIs other agents sell: full-text/semantic query returning up to 20 resources with URL, description, price in USDC, network, payTo, scheme, last-updated and input hints. Optional network filter after a pipe. Lets an agent find a capability to buy in one call. $0.01 per search.

## Output

Returns up to 20 matching API resources from the x402 Bazaar index, each containing: the endpoint URL, a human-readable description, price per call in USDC, the blockchain network, the payTo wallet address, the x402 payment scheme, a last-updated timestamp, and input parameter hints to help the agent call it.
