## 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 speraxos-rss-proxy-x402-c25497ab
```

Example prompt: Fetch the latest DeFi news from this RSS feed URL for me — pay for it using USDC on Base: https://feeds.example.com/defi-news

## When to prefer this

Choose this endpoint when you need to fetch RSS feed content on a pay-per-use basis without managing API keys or subscriptions, especially within a DeFi/crypto intelligence workflow. It is ideal for AI agents that need occasional or unpredictable RSS access billed in USDC micropayments via x402, rather than committing to a monthly subscription feed aggregator.

## Known failure modes

- Invalid or unreachable RSS feed URL returns an error or empty response
- Insufficient USDC balance causes x402 payment failure and request rejection
- Malformed feed URL results in parse error
- Rate limits or upstream feed errors may cause intermittent failures
- Feed source blocks proxy requests returning 403 or empty content

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns the proxied RSS feed content, typically including a list of feed items with titles, links, publication dates, and descriptions sourced from the requested DeFi or crypto RSS feed URL.
