How this service works
Call when an agent needs table header text via th from a public page or HTML (SSRF-safe). Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/css-th first.
Output
Returns the text content of all <th> elements found within the page or HTML input, allowing agents to understand table column structure without parsing full HTML manually. The response is SSRF-safe and covers all header cells present on the page.
Example use cases
Extract column names from data portal
“Go to https://data.gov/dataset/statistics and pull out all the table header texts so I can see what columns are available before I download the data.”
Parse headers from pasted HTML
“I have this chunk of HTML with a pricing table in it — can you extract all the th elements and tell me what the column headers are? Here's the HTML: <table><thead><tr><th>Plan</th><th>Price</th><th>Features</th></tr></thead></table>”
Identify table structure on competitor site
“Check https://competitor.com/pricing and extract all the table header cells so I know how they've structured their comparison table.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-th?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly extract table header (th) text from a known public URL or a known HTML string without writing custom parsing logic. It is SSRF-safe, making it suitable for agent pipelines that must not expose internal network resources. It costs $0.005 USDC per call; consider the free POST /v1/sandbox/css-th endpoint first if available for testing or cost savings.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with an error
- Page has no <th> elements — returns empty result set
- HTML input exceeds 200,000 character limit — rejected with validation error
- URL string shorter than 8 characters or malformed — rejected
- SSRF-blocked private/internal IP ranges — request denied for security
- Dynamic JavaScript-rendered tables may not have th elements in the static HTML
- Payment of $0.005 USDC not provided — returns 402 Payment Required
