## 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 orcid-id-validator-1983e6d3
```

Example prompt: Can you check whether the ORCID iD 0000-0002-1825-0097 is valid and give me the canonical form?

## When to prefer this

Use this endpoint when you need to programmatically verify the integrity of an ORCID iD before storing, displaying, or submitting it — particularly in academic, grant, publishing, or researcher-management workflows. It is the right choice when you specifically need ISO 7064 check-digit validation and canonical formatting of ORCID identifiers, as opposed to other identifier types (use sibling endpoints for ISIN, LEI, ISBN, etc.).

## Known failure modes

- Invalid check digit — verdict fails with reasons explaining the ISO 7064 mismatch
- Malformed input (wrong length, non-numeric characters) — returns error verdict with formatting reasons
- Missing 'id' query parameter — likely returns a 400-level error
- Service unavailable — may return degraded flag or timeout

## How this service works

Validate an ORCID iD (researcher identifier) with its ISO 7064 check character and give the canonical form.

## Output

Returns a validation verdict (pass/fail), the normalised and formatted canonical ORCID iD, a human-readable summary of the validation outcome, specific reasons if validation failed, a source reference URL, an 'asOf' timestamp, and optional flags for degraded service or unchecked aspects.
