How this service works
FetchWeb provides pay-per-call web metadata for AI agents. Use FetchWeb to quickly inspect a URL — title, description, canonical URL, language and estimated token size — before performing web extraction, web research or LLM processing, so an agent can judge whether a page is relevant.
Output
Returns a JSON object containing the page title, meta description, canonical URL, detected language (or null), word count, estimated token count, and a boolean indicating whether a charge was applied.
Example use cases
Pre-filter URLs before deep scrape
“I have a list of 50 URLs I might want to scrape, but I only want the English ones about climate change. Can you fetch the metadata for https://reuters.com/environment/story-123 to check the title, description, and language before I commit to a full extraction?”
Token budget estimation before LLM call
“I'm about to send a webpage into my LLM pipeline — can you first check https://techcrunch.com/2024/05/some-article and tell me roughly how many tokens it would use so I can decide if it fits within my context window?”
Canonical URL resolution for deduplication
“I think I have duplicate pages in my crawl — can you pull the metadata for https://example.com/page?utm_source=twitter and tell me what the canonical URL is so I can check if it's already in my index?”
Technical details
Endpoint
GEThttps://fetchweb.net/api/public/metadata?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly triage or filter URLs before committing to more expensive full-page extraction. It is ideal for relevance checks, token budget estimation, deduplication via canonical URLs, and language filtering. Prefer it over full-extraction sibling endpoints when you don't yet need the page body, headings, or markdown — just the signals needed to decide whether deeper processing is worthwhile.
Side effects
- URL is unreachable or returns a non-200 status — likely returns an error or empty fields
- Page has no meta description or title — fields may be empty strings
- Paywalled or bot-blocked pages may return incomplete or misleading metadata
- Language detection may be null for very short or binary pages
- Network timeout on slow-loading pages
