## 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 kihustle-record-linkage-api-8c97cda6 -d '<json body>'
```

Example prompt: I have two lists of customer records — one from our CRM and one from our billing system — and I want to link them together using the 'email' field as the key. Can you match them up and tell me which records correspond to each other?

## When to prefer this

Choose this endpoint when you need to programmatically match or reconcile two separate datasets using a common key field, especially in automated pipelines where entity resolution or record deduplication is required. It is suitable for lightweight, per-call record linkage tasks rather than bulk batch processing of massive datasets.

## Known failure modes

- Missing or invalid key_field causes linkage to fail or return no matches
- Empty records_a or records_b arrays result in no linkage output
- Mismatched data types on the key field across the two record sets may prevent matches
- Malformed record objects in either array may cause a processing error
- Very large record sets may time out or exceed payload limits

## Output

Returns a JSON object with a 'result' field indicating the outcome of the record linkage operation and a 'status' field confirming success or failure. The response indicates whether the two record sets were processed and linked successfully, though detailed matched pairs may be embedded in the result field.
