## 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 grant-records-required-field-coverage-check-6da6742e -d '<json body>'
```

Example prompt: Check these 10 public grant records and tell me which ones are missing any of the required fields: issuer, subject, agency, and jurisdiction — I need to know which rows have null pins before I process them further.

## When to prefer this

Use this endpoint when you need a lightweight, per-row check of whether required issuer/subject or producer/work pins are present in grant record data — particularly when preparing grant datasets for downstream processing, auditing completeness before publication, or validating synthetic or public grant data against a caller-defined set of required fields. Prefer this over a full credential validation service when you only need presence/null checks, not authenticity certification.

## Known failure modes

- Rows array empty or exceeds 32-item limit — request rejected
- Required fields list empty or exceeds 8 items — validation error
- nonpersonalMetadata not set to true — request rejected
- dataClass not one of 'public' or 'synthetic' — enum validation error
- Malformed row objects that cannot be parsed — analysis skipped or error returned

## How this service works

Check presence of required issuer/subject or producer/work pins; null is missing, not an invalid credential or artifact for agency/opportunity/program/jurisdiction/revision-pinned grant Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a per-row analysis indicating which required fields are present or null (missing) in each supplied grant record, without performing independent certification — analysis is based solely on the supplied data.
