Same proxy as netlify/functions/ai.mjs, rebuilt as a standalone Bun service on
the CVM host so AI calls stop spending Netlify compute/bandwidth credits and
the sats-paid Routstr key lives on our box.
- ai-proxy/server.ts: Bun.serve on 127.0.0.1:8787 — NIP-98 + Pro gate, model
allowlist, per-IP throttle, /api/ai + /api/ai/status. Own tsconfig
(typecheck:ai in npm test); eslint-ignored like cvm-server.
- ai-proxy/{package.json,.env.example,skatespots-ai.service,Caddyfile,DEPLOY.md}.
- scripts/deploy-ai-proxy.sh (npm run deploy:ai): scp + bun install + unit +
restart, mirroring deploy-cvm.sh.
- Client: one place decides the AI base, src/lib/sasquatchAi.ts (also the NIP-98
u tag). Defaults unchanged (/api/ai on Netlify); set VITE_SASQUATCH_AI_BASE to
move it. Fully reversible.
Deployed and verified on the host: /api/ai/status returns the live Routstr
balance. Public TLS (DNS + Caddy) is the remaining step before switching the app
over, so no client behaviour changes yet.
Load protection (public read-only endpoint — protects relays + this box):
- Per-pubkey sliding-window throttle and in-flight cap via inbound middleware.
The transport can't return a JSON-RPC error, so over-budget callers are dropped
and time out (logged).
- Global semaphore caps concurrent upstream relay queries.
- Short-TTL cache keyed by filter set, so repeated identical queries (e.g. a
burst of get_community_stats) don't re-hit the relays.
- All tunable via CVM_RATE_* / CVM_MAX_* / CVM_QUERY_CACHE_MS (documented in
.env.example); maps pruned by a janitor.
CI:
- cvm-server/tsconfig.json type-checks the standalone server; new
typecheck:cvm / check:cvm scripts, with typecheck:cvm wired into npm test so
the server can't rot unnoticed (it was excluded from tsc + eslint).
