## 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 farcaster-intel-api-channel-intelligence-46c4792e
```

Example prompt: What's going on in the Farcaster /base channel — who are the top casters, what topics are trending, and what's the most reacted cast recently?

## When to prefer this

Use this endpoint when you need structured, pre-aggregated analytics about a specific Farcaster channel — including who the top contributors are, what's trending, and engagement benchmarks — without having to query the raw Farcaster API yourself. Ideal for AI agents that need channel-level social intelligence on demand with pay-per-query pricing via x402 on Base.

## Known failure modes

- Invalid or non-existent channel name returns error or empty result
- Payment failure (402) if USDC/x402 payment not properly included
- Rate limiting or upstream Farcaster API unavailability
- Channel with very low activity may return sparse data (low cast_count_sampled)
- Network timeout from Vercel edge function

## How this service works

Structured Farcaster intelligence for AI agents. Pay per query in USDC on Base via x402.

## Output

Returns a JSON object with: channel_id, fetched_at timestamp, a natural-language summary, an array of trending topics, top_casters list (fid, username, cast_count, total_reactions), top_cast details (text, author, reactions, timestamp), average engagement score, and sampled cast count.
