## 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 fresh CoinDesk news headlines on a pay-per-call basis without a subscription, particularly in automated agent workflows that need crypto news infrequently or on-demand. It is ideal for agents already operating in the x402 micropayment ecosystem on Base and needing lightweight, structured headline data rather than full article content.

## Known failure modes

- Payment failure if x402 USDC transaction on Base is not completed or wallet has insufficient funds
- Rate limiting or upstream CoinDesk feed unavailability returning empty or stale results
- Malformed response if the upstream RSS/API feed changes structure
- Network timeout from the Cloudflare Worker reaching the CoinDesk source
