How this service works
URL syntax validator. Takes one absolute HTTP or HTTPS URL and returns its normalized form, or a specific error code: unparseable, unsupported scheme, embedded credentials, IP literal, or local/metadata hostname. Never contacts the destination, so it is fast and side-effect free. Useful for cleaning URLs from user input, scraped pages, or LLM output before fetching them.
Output
Returns either the normalized canonical form of a valid HTTP/HTTPS URL, or a specific structured error code indicating the exact reason for rejection: unparseable, unsupported scheme, embedded credentials detected, IP literal address, or local/metadata hostname. No network request is made to the destination URL.
Example use cases
Sanitizing user-submitted URLs
“A user just pasted this URL into our form: 'ftp://files.example.com/report.pdf' — can you validate it and tell me if it's a supported HTTP/HTTPS URL or flag the exact problem?”
Cleaning LLM-generated URLs
“The AI just produced this URL as output: 'https://169.254.169.254/latest/meta-data/' — check whether it's syntactically valid and safe to fetch, and give me the specific error code if it's not.”
Rejecting credentials in scraped URLs
“I scraped this URL from a third-party page: 'https://user:secret@api.example.com/endpoint' — validate it and flag if there are embedded credentials or anything else that would make it unsafe to use.”
Technical details
Endpoint
POSThttps://verifylite.hydratinghealingtouch.workers.dev/verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, side-effect-free URL syntax validation before fetching or storing a URL — especially to guard against SSRF attacks, credential leakage, or malformed input from users, scrapers, or LLMs. Prefer this over live safety-check endpoints when you don't want to make any outbound network request to the target URL. Ideal as a first-pass filter in a pipeline before more expensive checks.
Side effects
- Malformed JSON input returns a parsing error
- Non-absolute URL (e.g. relative path) returns unparseable error
- URL with unsupported scheme (e.g. ftp://, file://) returns unsupported scheme error
- URL containing username/password returns embedded credentials error
- URL pointing to an IP literal (e.g. [::1] or 1.2.3.4) returns IP literal error
- URL pointing to localhost, 127.0.0.1, or cloud metadata endpoints returns local/metadata hostname error
- Missing required 'url' field returns a validation/parameter error
- Payment failure or insufficient USDC balance returns x402 payment error
