How this service works
Call when an agent needs text of //code via //code from a public page or HTML (SSRF-safe). Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/xpath-code first.
Output
Returns the extracted text or code content matched by the XPath expression from either a fetched public URL or provided raw HTML string. Output is the raw text content of the matched node(s).
Example use cases
Extract code from documentation page
“Pull the Python code example from https://docs.someapi.com/getting-started — it's inside the element at XPath //div[@id='python-example']//code.”
Scrape article text from news site
“Get me the main article body text from https://news.example.com/article/12345 — it should be at XPath //article//p, concatenated together.”
Parse raw HTML snippet for a value
“I have this HTML from a product page — can you extract the price text using XPath //span[@class='price'] from it?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-code?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract specific text or code from a known public web page or a chunk of HTML using a precise XPath expression, and you want SSRF-safe fetching with a predictable $0.01 USDC cost. Prefer the free sandbox POST /v1/sandbox/xpath-code for testing. Choose this over CSS-selector-based scrapers when XPath specificity is required.
Side effects
- URL is not publicly accessible or returns non-200 status — endpoint may return an error or empty result
- XPath expression matches no nodes — returns empty or null result
- HTML content exceeds 200,000 character limit — request rejected
- URL triggers SSRF protection (private/internal IP ranges) — blocked and returns error
- Malformed XPath expression — returns parse error
- URL parameter too short (<8 chars) or too long (>2048 chars) — schema validation failure
