How this service works
Call when an agent needs figcaption text via figcaption from a public page or HTML (SSRF-safe). Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/css-figcaption first.
Output
Returns an array or collection of figcaption text strings found within figure elements on the specified page or HTML input, covering all matched figcaption elements in document order.
Example use cases
Image caption audit for accessibility
“Go to https://www.museum-site.org/exhibits and extract all the figcaption text so I can review whether every image has a proper descriptive caption.”
Scraping recipe photo descriptions
“Fetch the page at https://www.foodblog.com/pasta-recipes and pull out all the figcaption text — I want to see how each dish photo is described.”
Extracting captions from raw HTML
“I have this HTML snippet from a product page — can you extract all the figcaption text from it so I can catalog the product image descriptions?”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-figcaption?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract specifically figcaption text from HTML figure elements — ideal for accessibility audits, media metadata collection, content indexing, or any workflow where image captions in structured HTML are the target. Prefer over generic scraping tools when you want a focused, CSS-selector-level extraction that is SSRF-safe and priced per call.
Side effects

- No figcaption elements found on the page, returning an empty result
- SSRF-blocked private/internal URLs rejected for security reasons
- Malformed URL under 8 characters rejected by schema validation
- Page returns non-HTML content (e.g. PDF, JSON), yielding no matches
