## 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 x-twitter-handle-to-contract-address-matcher-fe532f66
```

Example prompt: Can you check if the Twitter handle @RugCoinOfficial actually matches the contract address 0xabc123def456abc123def456abc123def456abc1 — I want to know if it's a MATCH, PARTIAL, or NO_MATCH before I buy in.

## When to prefer this

Use this endpoint when you need a quick, low-cost (~$0.01) social signal cross-check between an X/Twitter handle and a token contract address as part of a token diligence workflow. It is ideal for agents that need to verify whether a crypto project's Twitter account is actually associated with the contract address being promoted, helping detect impersonators or mismatched promotional accounts. Prefer this over manual timeline scraping when you want a structured MATCH/PARTIAL/NO_MATCH/UNKNOWN signal without building your own scraper. It pairs naturally with the sibling endpoints on the same host for full LP, ERC20, and risk gate checks.

## Known failure modes

- UNKNOWN returned when twiscan scrape is unavailable or rate-limited
- handle not found or suspended X account returns UNKNOWN
- invalid contract address format may result in error or UNKNOWN
- rate limiting or scrape failures at the twiscan mirror layer cause UNKNOWN responses
- payment failure (non-402-compliant client) will block the call entirely

## How this service works

Best-effort X/Twitter ↔ contract-address match via twiscan public mirror. Returns MATCH|PARTIAL|NO_MATCH|UNKNOWN (honest UNKNOWN if scrape unavailable). Query handle= (required) & optional ca=. ~$0.01.

## Output

Returns one of four string values: MATCH (strong positive correlation found between the handle's timeline and the contract address), PARTIAL (some association found but not conclusive), NO_MATCH (no association detected), or UNKNOWN (scrape was unavailable and result cannot be determined). The response is a best-effort determination based on publicly available X timeline data via the twiscan mirror.
