## 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 quotient-x-account-profiler-c9b27791 -d '<json body>'
```

Example prompt: Can you build a full profile of @naval on X — his interests, beliefs, risk posture, and information-processing style — using the trading focus and looking back 180 days? I want every claim backed by actual posts.

## When to prefer this

Choose this endpoint when you need a deep, citation-backed behavioral and psychological profile of a specific X account rather than a simple follower count, engagement metrics, or raw post retrieval. It is especially valuable for personalization, due diligence on influencers or traders, understanding someone's worldview before outreach, or building prediction-market context around a public figure's expressed views. Prefer this over generic social media analytics tools when you need interpretive claims (beliefs, risk posture) grounded in actual post evidence rather than surface statistics.

## Known failure modes

- Invalid or non-existent X handle returns an error
- lookback_days outside 14–365 range rejected with validation error
- Account is private or has insufficient post history — sparse or empty profile returned
- Grok search exhausted within 3-turn ceiling without full coverage — partial profile returned
- Cache hit may return slightly stale data (up to 30 days old)
- Payment failure via x402 prevents call execution

## How this service works

Use this to build a citation-grounded profile of one X account. A high-reasoning Grok agent adaptively searches up to 365 days of history across topics and time periods within a hard three-turn ceiling, then returns evidenced interests, beliefs, behavioural tendencies, risk posture, information-processing style, and personalization hints. Every claim cites supporting posts. Matching results are shared from Quotient's cache while less than 30 days old.

## Output

A structured profile of the X account containing evidenced interests, beliefs, behavioral tendencies, risk posture, information-processing style, and personalization hints — with every claim linked to specific supporting posts from the account's history. Results may be served from Quotient's cache if a matching profile was generated within the last 30 days.
