## 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 context-dev-transaction-identifier-61c2ba00
```

Example prompt: I have a bank transaction titled 'AMZN Mktp US*AB12C3456' — can you identify which brand or merchant this belongs to and give me their company details?

## When to prefer this

Use this endpoint when you need to identify or enrich financial transaction data by resolving a raw transaction title string (such as those found in bank statements or payment records) to a known brand or merchant. Prefer this over generic brand lookup endpoints when the input is specifically a transaction title rather than a domain or email.

## Known failure modes

- Transaction title does not match any known brand — returns empty or null result
- Ambiguous transaction title matching multiple merchants — low confidence result
- Rate limit exceeded — HTTP 429
- Invalid or missing transaction title parameter — HTTP 400
- Service unavailable — HTTP 500

## How this service works

Endpoint specially designed for platforms that want to identify transaction data by the transaction title.

## Output

Returns brand and context data associated with the identified merchant or company behind the given transaction title, including company name, domain, and other available brand attributes.
