- netlify/functions/ai.mjs: optional Pro enforcement (SASQUATCH_REQUIRE_PRO=1).
Requires a NIP-98 kind-27235 auth header (x-sasquatch-auth) and, unless the
caller is a platform owner, an active Pro pass (x-sasquatch-pro = a
provider-authored zap receipt) verified OFFLINE — signature, user binding,
platform tag, and paid-amount → tier. Off by default.
- src/lib/proAuth.ts: signs the NIP-98 once per session (no Amber popup per
message) and attaches the Pro receipt.
- sasquatchBrain: threads auth headers through the proxy (streaming + non).
- useSasquatchPro: exposes the winning receipt event.
- Verified: 200 with the gate off, 401 with it on (env reset afterwards).
- netlify/functions/ai.mjs: POST /api/ai runs against Netlify's AI Gateway —
Netlify injects OPENROUTER_API_KEY + OPENROUTER_BASE_URL into Functions, so no
key is managed or shipped. Curated model allowlist, best-effort per-IP
throttle, CORS for web + Capacitor, and SSE streamed straight through.
- sasquatchBrain: call the proxy instead of OpenRouter directly; drop
VITE_OPENROUTER_API_KEY entirely; PROXY_MODELS set to the slugs that actually
work via the gateway (its ZDR policy blocks gemini/anthropic/gpt-4o-mini).
- netlify.toml: [functions] directory.
- Verified in production: POST https://skate-spots.org/api/ai -> 200.
