## 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-181df31a -d '<json body>'
```

Example prompt: I have two lists of customer records — one from our CRM and one from our billing system — can you link them together using 'email' as the key field so I can see which records match across both datasets?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call record linkage operation between two structured datasets using a common key field, especially in automated pipelines where cost control matters at $0.003 per call. Suitable for small-to-medium dataset reconciliation tasks without needing to set up a full ETL pipeline or data warehouse join.

## Known failure modes

- Missing or invalid key_field causes unresolvable linkage and likely error response
- Empty or malformed records_a or records_b arrays may result in no matches or processing failure
- Records lacking the specified key_field value will be skipped or cause partial results
- Payment failure via x402 protocol returns 402 before processing begins
- Mismatched data types on the key field across datasets may result in zero matches
