GET /api/compare

live

Multi-Token Comparison (2 mints). Watchdog scores for 2-10 tokens side by side in one request, priced per mint and cheaper than calling /api/token once per mint since the payload is lighter. Pass a comma-separated mints query param.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
