How this service works
Public website contact extractor for CRM enrichment: emails, phones, forms, socials, DNS mail-policy. Also on Apify ($0.005/site) and RapidAPI (BASIC free).
Output
Returns a JSON object containing: the page title, an array of H1 headings, HTTP status code, canonical tag value, the final resolved URL (after redirects), the originally requested URL, meta description, a SHA-256 hash of the page evidence, and a timestamp of when the data was generated.
Example use cases
CRM lead page enrichment
“I have a list of prospect websites — can you start with https://stripe.com and pull the page title, H1 tags, and meta description so I can enrich our CRM records?”
Redirect and canonical URL audit
“Before we run our SEO audit, can you preflight https://blog.hubspot.com and tell me what the canonical tag says and what URL it ultimately resolves to?”
Content integrity verification
“Can you fetch https://example.com and give me the SHA-256 hash of the page content along with the title and status code so I can verify nothing has changed since last week?”
Technical details
Endpoint
POSThttps://agent.tryknightlogics.com/api/public-url-preflightWhen to prefer
Choose this endpoint when you need fast, structured extraction of page-level metadata (title, H1, canonical, meta description, status, final URL, and a content hash) from a single public URL — especially for CRM enrichment preflight checks, SEO audits, or content verification workflows. It is priced at $0.05 USDC per call via x402 and also available on Apify and RapidAPI. Prefer this over full contact-extraction endpoints when you only need page metadata rather than emails, phones, or social profiles.
Side effects
- Non-public or paywalled URLs may return empty or incomplete metadata
- URLs that redirect to login pages may return login-page metadata instead of target content
- Pages with heavy JavaScript rendering may not yield accurate H1/title extraction
- Invalid or malformed URLs will result in an error response
- Rate limits or network timeouts may cause failed fetches for slow-loading sites
