## 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 one-engine-records-pick-t7-78457fc2 -d '<json body>'
```

Example prompt: I have a batch of up to 500 JSON records and I only want to keep the 'id', 'name', and 'email' fields — can you pick just those keys from each record, rename 'email' to 'contact', and fill in 'unknown' as the default for any missing name?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call JSON field projection utility — especially inside agent pipelines where you want to strip, rename, or default-fill fields in batches of up to 500 records without spinning up custom transformation logic. Ideal when cost predictability ($0.0065/call) and simplicity matter more than heavy ETL features.

## Known failure modes

- Missing 'records' field causes validation error
- Records array exceeding 500 items may be rejected or truncated
- Malformed JSON in records array causes parse failure
- Payment failure via x402 if USDC balance is insufficient
- Rename map referencing non-existent keys silently skips those mappings

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object (or array) containing only the selected, renamed, and default-filled fields from the input records — effectively a projection of the original dataset.
