## 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 xspy-pro-dc93a5e1
```

Example prompt: Pull up the cached token CA history for Twitter user elonmusk — I want to see all the contract addresses they've ever mentioned in their tweets.

## When to prefer this

Prefer this endpoint over the real-time synchronous crawl version when you need CA history for a Twitter user and can tolerate potentially cached/slightly stale data. It costs 50 credits instead of 100, making it more economical for bulk lookups or when freshness is not critical. Choose the real-time endpoint when you need the absolute latest tweets including very recent CA mentions.

## Known failure modes

- Username not found or account is private — returns 404 or empty result
- Cache miss — no cached data available yet for this username, may return empty or stale data
- Invalid Twitter handle format — returns 400 validation error
- Insufficient credits (50 credits required) — returns 402 payment required
- Rate limiting or service unavailability — returns 429 or 503

## How this service works

Cached lookup of a Twitter/X account's recent tweets mentioning token contract addresses (CAs), with detected chain and address. Fast.

## Output

Returns a list of token contract addresses (CAs) that the specified Twitter/X user has mentioned or shared in their tweets, served from cache for faster and cheaper results (50 credits vs 100 for real-time).
