## 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`):

## When to prefer this

Choose this endpoint when you need a pay-per-call web search with crypto micropayment settlement via x402 on Base, and want to avoid subscription-based search APIs. It is particularly suited for AI agents that already operate in the x402 ecosystem and need lightweight, per-query web search without committing to a traditional API key or monthly plan.

## Known failure modes

- Missing required 'q' query parameter results in an error or empty results
- Payment failure or insufficient USDC balance causes a 402 Payment Required response
- Network or upstream search provider outage returns a 5xx error
- Invalid 'type' or 'method' fields in the input object cause request rejection
- Result count exceeds available results, returning fewer items than requested

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output
