With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability delx-page-links-summary-a57e5970 -d '' ``` Example prompt: Extract all the href links from this HTML I already have and give me a summary of them — limit it to the first 50 links: ... ## When to prefer this Use this endpoint when you already hold the raw HTML and want fast, stateless, local extraction of href links without triggering any network requests or web fetches. Prefer it for preflight checks before crawling, for auditing links in HTML snippets, or when you need deterministic link enumeration without side effects. It is ideal for agents that have already downloaded HTML and need to inspect its link structure cheaply and quickly. ## Known failure modes - Malformed or empty HTML input returns an empty link list or parsing error - Limit parameter set to zero or negative may return no results or an error - Extremely large HTML strings may exceed memory or processing constraints - HTML with no anchor tags returns an empty result set - Non-HTML content passed as the html field may produce empty or unexpected output ## How this service works Extract href links from caller-held HTML without network access — first-party local utility for agent preflight and proven micro-utils expansion. Returns deterministic machine-readable JSON for $0.002 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, no web search, no live RPC, and no mediagen. Results are advisory; the caller owns authorization, budgets, and production controls. Sibling of Delx routes that already… ## Output A deterministic JSON object listing all extracted href link values found in the provided HTML, up to the specified limit, along with a count and any relevant metadata about the links discovered — all computed locally with no network access. ## Request schema (JSON Schema) ```json { "type": "object", "properties": { "html": { "type": "string", "description": "Input field: html." }, "limit": { "type": "integer", "description": "Input field: limit." } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "ok": true, "note": "Local HTML regex extract; not a browser", "count": 2, "links": [ "https://example.com", "/about" ], "schema": "delx/util-page-links-summary/v1", "truncated": false } } ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/delx-page-links-summary-a57e5970/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from api.delx.ai](https://www.zero.xyz/host/api.delx.ai/llms.txt)
