Built 7 B2B APIs in 9 days — what should I add next?

Hey everyone! 👋

I built JSONexLab — 7 B2B APIs for trade, finance, compliance, all on the same stack (Cloudflare Workers + D1 + KV + R2).

The problem: small trade/fintech teams spend $500-2000/mo on separate vendors for HS codes, sanctions screening, document parsing, finance validators. I bundled them into one platform with free tiers.

What's live:

• HS Codes Classifier — AI classification (500 products)

• Compliance Engine — OFAC/UK/EU/UN + PEP + GLEIF (33K records)

• Docs-to-JSON — invoices/receipts/contracts → JSON

• Finance Validators — IBAN/VAT/SWIFT/LEI/Card

• Watch Engine — currency + VAT + tariff monitors

• Creator Engine — promise extraction from contracts

• ScopeGuard — sanctions monitoring with webhooks

Also shipped 5 MCP servers to the official Model Context Protocol Registry.

Launching on Product Hunt today — would love your feedback:
