How this service works
Call when an agent needs option text via option from a public page or HTML (SSRF-safe). Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/css-option first.
Output
Returns the text content of the matched HTML option element from the provided URL or raw HTML input, extracted safely without SSRF risk.
Example use cases
Scrape dropdown values from a form
“Go to https://shop.example.com/products and extract the text of the option element matching 'select#size option[value="M"]' so I can see what medium size label they use.”
Check option text from raw HTML snippet
“I have this HTML snippet from a page — can you pull out the text of the option that matches 'select.currency option:nth-child(2)'? Here's the HTML: <select class='currency'><option>USD</option><option>EUR</option></select>”
Verify form option label on live page
“Can you check what text appears in the option matching 'select#plan option[value="pro"]' on https://billing.myapp.io/signup? I want to confirm the label shown to users.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-option?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to extract the text of a specific HTML option element from a live public URL or a raw HTML string, and SSRF safety is required. Prefer the unpaid sandbox POST /v1/sandbox/css-option first for testing; use this paid endpoint for production calls where reliability matters.
Side effects
- URL is unreachable or returns non-200 response — extraction fails
- CSS selector matches no option element — empty or null result returned
- HTML content exceeds 200,000 character limit — request rejected
- SSRF-blocked URL (internal/private network addresses) — request refused
- Malformed HTML prevents proper parsing — unexpected or empty result
