How this service works
Call when an agent needs img alt values extracted from a public page or HTML (SSRF-safe). Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/profile-img-alt first.
Output
A list or structured collection of alt attribute values extracted from img tags found in the provided URL or HTML. May include empty strings where alt attributes are present but blank, and may omit images with no alt attribute.
Example use cases
Accessibility audit for a webpage
“Check https://mycompany.com/about and extract all the img alt text values so I can audit whether our images have proper accessibility descriptions.”
Alt text extraction from pasted HTML
“I have this HTML snippet from a product page — can you pull out all the image alt values from it so I know what text is associated with each product image?”
SEO image metadata review
“Go to https://blog.example.com/latest-post and get me all the alt text values from the images — I want to see if they're using good keywords.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-img-alt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically extract img alt attribute values from a public webpage URL or raw HTML string, especially in agentic pipelines requiring SSRF-safe access. Prefer the free sandbox POST /v1/sandbox/profile-img-alt endpoint first if available; fall back to this paid endpoint when the sandbox is unavailable or rate-limited.
Side effects
- URL is not publicly accessible or returns non-200 status — extraction fails
- SSRF protection blocks private/internal IP ranges or localhost URLs
- HTML input exceeds 200,000 character limit — request rejected
- No img tags with alt attributes found — returns empty result
- Malformed HTML may cause incomplete parsing
- Payment of exactly $0.01 USDC required; missing or incorrect payment causes rejection
