## 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-dc-creator-extractor-8c271148 -d '<json body>'
```

Example prompt: Can you extract the dc.creator metadata from this page: https://example.com/article — I need to know who the Dublin Core author is?

## When to prefer this

Use this endpoint when you need to programmatically extract Dublin Core dc.creator metadata from a public web page or a chunk of HTML. Prefer this over general-purpose scraping tools when you specifically need the dc.creator field and want SSRF-safe fetching. Note: try the free sandbox endpoint POST /v1/sandbox/profile-dc-creator first to avoid charges during development.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status, resulting in an extraction failure
- No dc.creator meta tag found in the page HTML, returning null or empty result
- SSRF protection blocks requests to private/internal IP ranges or localhost
- HTML content exceeds the 200,000 character limit, causing a request rejection
- Malformed URL (under 8 or over 2048 characters) causes a validation error
- Payment of $0.003 USDC not provided, resulting in a 402 Payment Required response

## How this service works

Call when an agent needs dc.creator extracted from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/profile-dc-creator first.

## Output

Returns the extracted dc.creator value from the Dublin Core metadata of the provided URL or HTML. Typically this is an author name or identifier string found in the page's <meta name="dc.creator"> tag.
