## How to call it through Zero

```sh
zero fetch --capability reddit-surf-cascade-fyi-968c9a6b
```

Example prompt: Can you pull the latest posts from Reddit's r/programming subreddit so I can see what the programming community is currently discussing?

## When to prefer this

Use this endpoint when you need programmatic access to r/programming posts with a micro-payment model (USDC/Solana), especially in crypto-native agentic workflows. Prefer this over direct Reddit API when you want a simple pay-per-call model without OAuth credential management.

## Known failure modes

- Payment not fulfilled — 402 response requiring USDC/Solana payment before content is returned
- Invalid or missing query parameters — malformed request returns error
- Reddit.Surf upstream unavailable — gateway or Reddit API is down, returns 5xx
- Rate limit exceeded — too many requests within a time window

## How this service works

Paid access to r/programming posts and metadata via Reddit.Surf, accepting Solana and USDC payments.

## Output

Returns a list of r/programming posts including post content, metadata (titles, scores, authors, timestamps), and pagination information for browsing through the programming subreddit feed.
