## 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-dc-title-extractor-c0b0da73 -d '<json body>'
```

Example prompt: Can you extract the dc.title metadata from this page — https://example.org/some-article — I need to know what Dublin Core title the page declares?

## When to prefer this

Use this endpoint when you specifically need the Dublin Core dc.title metadata field from a public webpage or raw HTML snippet. Prefer the free sandbox POST /v1/sandbox/profile-dc-title first if available to avoid the $0.002 USDC charge. Choose this over general-purpose scrapers when you only need the dc.title value and want SSRF-safe URL fetching.

## Known failure modes

- URL not reachable or returns non-200 status
- dc.title tag absent from the page HTML
- SSRF protection blocks private/internal IP ranges
- HTML input too large (exceeds 200,000 character limit)
- URL too short or malformed (below 8 characters)
- Payment not provided or insufficient USDC balance

## How this service works

Call when an agent needs dc.title extracted from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/profile-dc-title first.

## Output

Returns the extracted dc.title string value found in the page's Dublin Core metadata tags, sourced either by fetching the provided URL or parsing the supplied HTML directly.
