## 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

Example prompt: Find me alpha tweets about $SOL right now — I want early-signal posts that traders might be acting on, not just noise.

## When to prefer this

Choose this endpoint when you need to identify high-signal, early-information tweets about crypto or blockchain topics — specifically 'alpha' content that traders and degens act on before broader awareness. Prefer this over generic Twitter search when you want pre-filtered signal rather than raw volume, and when you need blockchain-native pay-per-use pricing via x402 micropayments.

## Known failure modes

- Missing or invalid query parameters returns an empty array or error
- No alpha tweets found for the given criteria returns an empty array
- Payment failure via x402 protocol blocks the request entirely
- Rate limiting or quota exhaustion results in a 402 or 429 error
- Overly broad or unsupported query parameters may return irrelevant results

## How this service works

Pay-per-use blockchain and social data for autonomous agents.

## Output

Returns an array of detected alpha tweets — high-signal social media posts identified as carrying early or insider-level information relevant to the queried blockchain or crypto topic. Each item in the array likely contains tweet content, metadata, and relevance signals.
