Canonical

GET /api/v1/canonical normalizes a URL and tells you which platform it belongs to — without fetching the post. No upstream request, no circuit breaker, cheap to call.

curl -H "Authorization: Bearer $FIXEM_API_KEY" \
  "https://fixem.be/api/v1/canonical?url=https://x.com/nasa/status/123?utm_source=share"

{
  "platform": "twitter",
  "canonicalUrl": "https://x.com/nasa/status/123"
}

Canonicalization strips tracking parameters and normalizes the host, so you get the clean, stable form of the URL.

When no adapter matches

{ "platform": "none" }

Use it for

• De-duplicating or grouping links before you resolve them.
• Cheaply checking whether a URL is supported at all.
• Getting a clean canonical URL without paying for a full resolve.

A missing or malformed url returns 400.
