How this service works
One heading or one selector instead of the whole page. A heading that is not found returns 200, an empty body and the list of headings that do exist.
Output
Returns the content of the specified heading section or CSS-selected elements as Markdown or plain text, up to the configured character limit. If the heading is not found, returns HTTP 200 with an empty body plus a list of all headings that exist on the page. If a CSS selector is used, returns up to 20 matched elements concatenated.
Example use cases
Extracting FAQ from documentation site
“Pull out only the 'FAQ' section from https://docs.someproduct.io/getting-started as markdown, using render mode so the page fully loads.”
Competitive pricing intelligence
“Fetch just the 'Pricing' heading section from https://competitor.com/plans as plain text — use residential egress in case they block datacenters.”
Scraping a specific element with CSS selector
“From https://news.site.com/article/123, extract the element matching the CSS selector '.article-summary' and return the result as markdown, up to 3000 characters.”
Technical details
Endpoint
POSThttps://readfetch.com/v1/section?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you only need a specific section or element from a page rather than the full content — it's more token-efficient and cheaper than fetching the whole page. Ideal when the target content is organized under a known heading or identifiable CSS class. Prefer the full-page scrape endpoints when the structure is unknown or you need the complete document. Use residential egress mode when the target site blocks datacenter IPs.
Side effects
- Heading not found: 200 response with empty body and list of available headings
- URL unreachable or returns non-200: error response indicating fetch failure
- JavaScript-heavy page content missing when using 'fast' mode instead of 'render'
- CSS selector matches no elements: empty result returned
- Datacenter IP blocked by target site when not using residential egress
- Content exceeds max_chars and is truncated at the limit
- Invalid CSS selector syntax causing a parse error
