## 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 agentshelf-syntexa-ch-orcid-regex-extractor-4336824d -d '<json body>'
```

Example prompt: Pull out all the ORCID iDs from this author bio section — up to 20 matches: 'Jane Smith (0000-0002-1825-0097) collaborated with Dr. Lee (0000-0001-5109-3700) on the 2023 paper.'

## When to prefer this

Use this endpoint when you need a fast, deterministic, offline regex-based extraction of ORCID iDs from text without any LLM inference or network calls. Prefer the free sandbox endpoint (/v1/sandbox/regex-orcid) for testing or when cost matters. Choose this paid endpoint for production pipelines where a reliable, billed-per-call contract is needed and you want guaranteed processing without rate-limiting concerns.

## Known failure modes

- Empty match list returned when no ORCID iDs are present in the text — still billed
- Input text exceeds 100,000 character limit — request rejected
- Input text is empty or missing — validation error
- More than 20 ORCID iDs in text — only first 20 returned, remainder silently truncated
- Payment of $0.005 USDC not provided or fails — x402 payment required error

## How this service works

Call when an agent needs ORCID iDs extracted from text, capped at 20 matches. An empty match list is billed. No network. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/regex-orcid first.

## Output

A list of up to 20 ORCID iD strings found in the input text, returned as regex matches. If no ORCID iDs are present, an empty match list is returned — and the call is still billed at $0.005 USDC.
