How this service works
Validate http(s) URL shape. Call when you preflight agent-held URLs before fetch/extract. Returns valid boolean for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns a boolean indicating whether the input string is a well-formed HTTP or HTTPS URL, determined locally using JSON-based rules with no network I/O or external API calls.
Example use cases
Preflight before web scraping
“I have this URL a user just submitted — 'https//missing-colon.com/path' — can you check if it's properly formed before I try to extract content from it?”
Validate user-submitted links
“A user pasted 'ftp://files.example.com/data.csv' into our form. Check whether it's a valid http or https URL shape so I know if it should be rejected before we queue it.”
Screen URLs in agent pipeline
“I've got a list of strings that might be URLs — check if 'https://valid-looking-site.com/article?id=42' has the right URL shape before we hand it off to the fetch step.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/is-url-shapeWhen to prefer
Choose this endpoint when you need a fast, cheap, stateless URL shape check before performing expensive operations like fetching or extracting page content. It is ideal for agent pipelines that need to preflight arbitrary or user-supplied URLs without making any network requests, incurring auth complexity, or retaining data. At $0.001 USDC it is suitable for high-volume screening in automated workflows.
Side effects
- Missing or empty 'url' field in request body returns an error or false result
- Non-string input types may cause a validation error
- URLs using non-http/https schemes (ftp, mailto) will return false
- Malformed request body returns HTTP 4xx error
- x402 payment failure or insufficient USDC balance blocks the request
