Code examples

# Option 1 — by certificate code
curl "https://certpath-gold.vercel.app/api/verify?code=CERTPATH-A1B2-C3D4"

# Option 2 — by certificate profile URL
curl "https://certpath-gold.vercel.app/api/verify?url=https%3A%2F%2Fcertpath-gold.vercel.app%2Fcertificate%2Fmedical-transcriptionist%2Fjane-doe%3Fcode%3DCERTPATH-A1B2-C3D4"

Notes

CORS: All origins are allowed — call this endpoint directly from browser JavaScript.
Authentication: None required. The API is intentionally public — certificates are designed to be shareable credentials.
Rate limiting: Please keep requests reasonable. Batch lookups aren't supported; query one certificate code per request.
Two ways to verify: pass ?code=CERTPATH-XXXX or the full ?url=https://certpath-gold.vercel.app/certificate/… — the code is extracted from the URL automatically.
Codes are case-insensitive: certpath-a1b2-c3d4 and CERTPATH-A1B2-C3D4 both work.
