Usage-based billing SDK for AI applications

A single Hacker News mention placed this repo at rank 12 on HN but nowhere else, producing a classic single-source spike with zero cross-platform traction.

Why now: HN's tiny 12-item pool and zero filtering for commercial posts let a single mention surface. No actual event.

• Only HN source with rank 12; zero GitHub, X, Reddit, Product Hunt, Dev.to, or Bluesky presence
• HN pool only has 12 total items — rank 12 means borderline inclusion, not front-page prominence
• 183 of 200 pool items are single_source — this is statistical baseline noise, not signal
• Ours rank 57 vs HN rank 44 shows no early detection; we lagged the one feed that noticed it

Considerations: HN rank 12 in a 12-item pool is essentially the minimum viable threshold. No GitHub velocity, no social amplification, no Product Hunt launch. Could be a founder's friend posting, or a Show HN that died. The 'usage-based billing for AI' space is crowded (Stripe, Orb, Metronome, Lago) — a new entrant needs distribution, not just a README.

EMERGING SIGNAL · Ignore: Do not track; revisit only if GitHub stars, X mentions, or Product Hunt launch appear within 14 days.
