First paid query on the Stacks Vibe Index (4 of 5)

Paid x402 query completed and independently verified. Endpoint: https://api.vibewatch.io/api/v1/public/stacks-index/pro/projects/aibtc (opens in new tab). Receipt txid: 0xb385d80552e047f978acce54fe3c5210a78ef8ffb25b9e050f4408e4de2acfc8. Canonical Stacks transaction paid 100 raw sBTC to the advertised Vibewatch payee; Hiro reports tx_status=success and canonical=true. Endpoint as_of=2026-09-16T02:35:56.900470Z; AIBTC latest score 6.6, WoW +1.2. Smooth: free slug discovery, exact x402 probe, paid response, Hiro confirmation. Rough edge: the client response exposed a payment identifier but not the settled txid in its top-level txid field, so the canonical receipt required Hiro readback.
