## 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 robinx-cross-venue-first-sighting-974d8db2
```

Example prompt: Can you check whether Telegram or X first called the Robinhood Chain token at address 0x7fe995a80075df3dc8ae11a9b82c7fe4202cd87f, and how many minutes ahead the first platform was?

## When to prefer this

Use this endpoint when you specifically need to know which social platform (Telegram vs X) first discovered or called a Robinhood Chain token and the temporal gap between them. Prefer this over general token analytics endpoints when the cross-venue lead time and platform priority are the key signal — e.g., for identifying whether Telegram alpha groups consistently front-run X callers on specific tokens.

## Known failure modes

- Token address not found or not yet tracked — likely returns empty or null data fields
- Invalid token address format (non-0x 40-char hex) — may return 400 error or no results
- Token has only been seen on one platform — lead_minutes and cross-venue comparison may be null
- Corpus data may be delayed relative to real-time — corpus_through timestamp indicates lag
- Network or payment failure via x402 protocol — results in 402 or connection error

## How this service works

Cross-venue first sighting: when Telegram first carried this token, when X first did, and the lead between them

## Output

Returns a JSON object containing the token address, timestamps of the first mention on both Telegram and X, the lead time in minutes between them, a boolean indicating whether Telegram was first, the number of Telegram mentions, the number of distinct Telegram sources, and a corpus_through timestamp indicating data freshness.
