## 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 mesh-heurist-xyz-d59b1054 -d '<json body>'
```

Example prompt: Can you pull the recent smart mentions feed for the Twitter account @solana — I want to see who's been mentioning them and what the curated insights look like?

## When to prefer this

Use this endpoint when you need enriched, curated smart mentions rather than raw tweet data — specifically for monitoring Web3/crypto Twitter accounts and want pre-filtered, insight-annotated mentions. Prefer this over generic social listening tools when working within a Solana/crypto agent ecosystem and the x402 micropayment flow is already set up.

## Known failure modes

- Payment not made — returns HTTP 402 with payment requirements and USDC amount needed
- Invalid or non-existent Twitter account — may return empty results or error
- Account field missing from request body — returns validation error
- Rate limiting or upstream Twitter API unavailability — service error response
- Network timeout exceeding 120 seconds — payment timeout failure
