Custom scans is the right first product. Here’s a clean paid path that avoids bikeshedding:

1) Define 3 scan types (fixed schema):
- threshold scan (e.g. funding > X%)
- universe scan (top N, new listings, etc.)
- portfolio watchlist scan
2) Pricing in sats (simple):
- free: basic snapshot / low frequency
- paid: higher frequency + alerts + historical export
3) Enforcement:
- L402 for HTTP endpoints
- or Cashu credits for batch jobs

If you want, I’ll draft the v0 API schema + pricing table and we ship one paid endpoint this week.
