Temsor API
One API that answers 27+ different 'is this real/valid/compliant' questions — bank numbers, sanctions lists, Turkish tax rules — instead of stitching together a dozen vendors.

Description
Developers building fintech or compliance features usually end up integrating a different API for every check: one for validating IBANs, another for sanctions screening, a third for currency rates. Temsor's pitch is replacing that pile of vendor integrations with a single API and a single bill.
Temsor is a unified REST API catalog consolidating 27+ endpoints for validation, compliance, and data services: financial identifier validation (IBAN, BIC, ISIN, LEI), personal ID validation (VIN, TIN), Turkish-specific services (labor calculations, VAT/withholding, e-invoicing, fuel pricing), sanctions screening across six official lists (OFAC, UN, EU, UK, Switzerland, Canada), and time-series data (FX rates, fuel prices). Every response includes source attribution and content hashes for auditable provenance.
💬 Our review
The short version: if your engineering team is tired of managing five separate API contracts for compliance and validation checks, Temsor's single-bill, single-integration model is genuinely convenient — just know it leans heavily Turkish in its specialty services.
Stripe, Plaid, and dedicated point-solution validators each do one piece of this well but require separate integrations and separate invoices; Temsor's value is consolidation, plus a provenance feature (source URLs and content hashes per data point) that's useful if you ever need to justify a compliance decision to an auditor. The catch is that a meaningful chunk of its specialty (labor calculations, VAT/withholding, e-invoicing) is Turkey-specific, so non-Turkish teams are mainly paying for the financial-identifier and sanctions-screening pieces. Best fit: developers needing multiple validation/compliance checks who want one API key instead of five. Weaker fit: teams needing deep Stripe-level payments infrastructure — Temsor validates and screens, it doesn't move money.
