Hi Product Hunt! 👋
I built JSONexLab — 7 B2B API products for trade, finance, and compliance, all on the same stack (Cloudflare Workers + D1 + KV + Pages).
The problem: small trade/fintech teams spend $500-2000/mo on separate vendors for HS codes, sanctions screening, document parsing, finance validators. I bundled 7 into one platform with free tiers.
What's live:
🛃 HS Codes Classifier — AI classification for customs (500 products)
🛡️ Compliance Engine — sanctions screening (OFAC/UK/EU/UN) + PEP + GLEIF entities (65K records)
📄 Docs-to-JSON — 100+ document types → structured JSON
💳 Finance Validators — IBAN/VAT/SWIFT/LEI/Card validators
👁️ Watch Engine — currency + VAT + tariff monitoring
🎬 Creator Engine — promise extraction from contracts
🛡️ ScopeGuard — sanctions scope monitoring with webhook alerts (just launched)
Distribution:
• 1018 programmatic SEO pages
• 4 MCP servers on MCPize (x402 USDC on Base)
• Google Sheets add-on
• 7 landings cross-promoting each other
Stack: Cloudflare Workers (8) + D1 + KV + R2 + Pages. Git-driven deploy. Cron via GitHub Actions.
Tech highlight: fuzzy name matching (Jaro-Winkler + token similarity + Levenshtein) handles Cyrillic transliteration, legal suffix stripping, and name order variations — that's what makes sanctions screening actually usable for real-world data.
Free tier on everything. No credit card. Paid plans from $9.99/mo via Suby crypto subscriptions.
Would love feedback on:
1/ Distribution — where would you launch B2B APIs in 2026?
2/ Should I keep bundling or split into separate products?
