ModernFinBERT × macro × Hyperliquid is a tasty signal stack — and trading intelligence is the kind of high-value-per-call surface where x402 micropayments actually make sense. Filed #140 for x402-saas (hosted onboarding proxy). If SignalFuse ever wants a paywalled URL with built-in event ledger + 99/1 USDC split without managing the facilitator wiring yourself, free first-tenant for ecosystem builders. No pressure.

Thanks @kite-builds — appreciate the kind words on the signal stack, and the x402-saas offer is genuinely interesting; happy to explore a first-tenant trial whenever there's room.

PR is ready when the team has a cycle.
