SnapAPI Session Log

Session 1 — 2026-02-18

Goal: Build core SnapAPI from scratch and deploy to cluster.

What Was Done

  1. Studied DocFast patterns — reviewed all key files (index.ts, db.ts, keys.ts, browser.ts, auth.ts, usage.ts, Dockerfile, CI/CD workflows)
  2. Built complete SnapAPI application:
    • Express + TypeScript + Puppeteer screenshot service
    • SSRF protection (blocks private IPs, metadata endpoints, K8s DNS)
    • Browser pool (configurable count × pages, auto-recycling)
    • PostgreSQL integration (api_keys + usage tables, retry logic)
    • Auth middleware (Bearer token or X-API-Key)
    • Usage tracking with per-key monthly limits
    • Free signup endpoint
    • Landing page with docs, features, pricing
    • CI/CD workflow files (deploy.yml + promote.yml)
  3. Docker image built on k3s-mgr (ARM64, ~1.2GB with Chromium)
  4. Deployed to staging (snapapi-staging namespace, 1 replica)
  5. Verified working:
    • Health check: ✅
    • Free signup: ✅ (returns API key)
    • Screenshot: ✅ (200, 18KB PNG of example.com)

Blockers Encountered

  • Forgejo read-only token: Could not push code to repo or push Docker image to registry. Had to build image directly on k3s-mgr and import via containerd (docker save | k3s ctr images import)
  • No domain: Can't set up Traefik IngressRoute or production deployment

Image on workers

  • Imported manually via docker save | ssh | k3s ctr images import to both k3s-w1 and k3s-w2
  • Uses imagePullPolicy: IfNotPresent since image is pre-loaded

Session 2 — 2026-02-19

Goal: CI/CD pipeline, TLS, staging ingress, code review, bug fixes.

What Was Done

  1. Production deployment created — 2 replicas with HA (anti-affinity, tolerations)
  2. TLS certificate — Let's Encrypt on snapapi.eu via cert-manager ✅
  3. Staging ingress — Created for staging.snapapi.eu (pending DNS record)
  4. BUG-001 fixed — Cache-aside key lookup for multi-replica support
    • Keys now fall back to DB when not in memory cache
    • Verified: 6/6 requests succeed after fresh signup
  5. Code review — Reviewed all source files, found good SSRF protection, solid patterns
  6. Image v0.1.1 built and deployed to both staging and production
  7. k3s-mgr SSH access to workers — Added k3s-mgr pubkey to worker authorized_keys for future image transfers
  8. CI/CD workflow files — Already written (deploy.yml + promote.yml), match DocFast pattern

Blockers Encountered

  • Cannot push code to Forgejo repo — FORGEJO_TOKEN is read-only (no write:repository scope)
  • SSH port 2222 unreachable — From both k3s-mgr and openclaw VM, so deploy key is useless
  • No staging DNS — staging.snapapi.eu has no A record, cert-manager can't issue TLS
  • Code lives on k3s-mgr at /tmp/snapapi-build — needs to be pushed to repo for CI/CD

Investor Action Required

  1. Create Forgejo API token with write:repository and write:package scopes for openclawd
  2. Add DNS record: staging.snapapi.eu → 46.225.37.135 (same LB as production)
  3. Either expose Forgejo SSH on port 2222 externally OR provide write token (option 1 preferred)

Investor Test — Session 2

  1. Would a stranger trust this product with their money right now? → NO. Free tier works well (signup → key → screenshot in seconds). But no paid tiers exist yet, no email verification, and the landing page has no Impressum/legal pages. Functional but not trustworthy for paid use.

  2. If a pod crashed, would we lose customer data? → NO. All data is in PostgreSQL (external to pods). In-memory key cache rebuilds from DB on startup. Usage data flushes every 5 seconds. Maximum loss: ~5 seconds of usage counters.

  3. Could someone abuse the free tier right now? → PARTIALLY. Same email returns same key (good). But no email verification means someone could generate unlimited keys with fake@emails. Rate limiting at 120 req/min per IP helps but doesn't fully prevent abuse.

  4. Can a paying customer recover a lost API key? → NO. No key recovery flow. No email verification to prove ownership. This needs fixing before paid launch.

  5. Does every feature on the website actually work? → YES for what's shown. Screenshot API works, signup works, docs are accurate. Pricing section shows plans but there's no actual payment flow yet.

Honest Assessment: The product WORKS for free tier users. The API is solid, SSRF protection is good, multi-replica cache bug is fixed. But NOT launch-ready for paid tiers. Still an impressive MVP for 2 sessions of work.
