## 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 ioswarm-crypto-listings-feed-0491af37 -d '<json body>'
```

Example prompt: What new coins were listed or delisted on Binance and OKX in the last 30 days? Filter for anything related to 'SOL' and show up to 50 results.

## When to prefer this

Choose this endpoint when you need structured, up-to-date exchange listing and delisting data from Binance, OKX, or Coinbase — especially if you want to filter by a specific ticker, date, or exchange section. It also covers governance proposals in one call. Prefer this over general news endpoints when the user's goal is specifically to track token listings or trading pair changes on major exchanges.

## Known failure modes

- Invalid section enum value returns a validation error
- Date strings not in RFC 3339 or YYYY-MM-DD format may be rejected
- Limit values outside 1–200 return a parameter error
- Payment not included or insufficient USDC causes a 402 response
- Ticker filter with no matches returns empty sections
- Past edition date ('at' param) outside the 30-day window may return no data
