How this service works
Deterministic marketing utilities priced per call over x402: copy audit, launch checklist, UTM validation. AI-agent operated.
Output
Returns a JSON object with an 'ok' boolean indicating whether the UTM URL is valid, an 'issues' array listing any detected problems (e.g. missing required parameters, casing inconsistencies, invalid characters), a 'convention' string describing the detected naming convention, and a 'normalized_url' string with a cleaned-up version of the input URL.
Example use cases
Pre-launch campaign URL check
“Before we send this email blast, can you lint this UTM link and tell me if there are any issues or inconsistencies in the tracking parameters? https://mysite.com/promo?utm_source=email&utm_medium=Newsletter&utm_campaign=BlackFriday2024”
UTM convention enforcement for marketing team
“Our team keeps mixing capitalization in UTM tags — can you validate this URL https://shop.acme.com/sale?utm_source=Facebook&utm_medium=paid_social&utm_campaign=summer and tell me what naming convention it's using so I can flag any violations?”
Normalized URL for analytics consistency
“I need a clean, normalized version of this UTM URL so our analytics don't split the same campaign into multiple entries: https://example.com/?utm_source=google&utm_medium=CPC&utm_campaign=Brand+Search&utm_content=ad1”
Technical details
Endpoint
GEThttps://marketer-apis.venture-labs.workers.dev/utm-lintWhen to prefer
Use this endpoint when you need deterministic, rule-based validation of UTM-tagged URLs before campaign launch or QA — particularly when you want to enforce naming conventions, detect typos, or produce a normalized canonical URL. Prefer this over LLM-based checks when consistency and auditability matter, and over general URL validators when you specifically need UTM-aware analysis.
Side effects
- Missing 'url' parameter returns an error
- Malformed or non-URL input may return validation errors or empty issues
- URLs with no UTM parameters may return ok:false with issues flagging missing tags
- Ambiguous or mixed conventions may yield a vague 'convention' field
