Didit Identity & Fraud API

Didit is an identity and fraud infrastructure company founded in 2023 in Barcelona by twin brothers Alberto and Alejandro Rosas and now headquartered in San Francisco. It targets fintechs, crypto platforms, marketplaces and other online businesses that find incumbent KYC vendors expensive and slow to integrate.

Through a single API, SDKs for web and mobile and an MCP server for AI agents, Didit offers more than 25 modules: document verification across 14,000+ document types from 220+ countries, passive liveness, 1:1 face match, NFC chip reading, age estimation, AML screening, transaction monitoring, crypto wallet screening, business verification, device and IP analysis, phone and email checks and reusable digital IDs. A workflow orchestrator combines modules into onboarding flows, and checks draw on more than 1,000 government data sources.

• ID verification: Checks 14,000+ document types from more than 220 countries.
• Passive liveness and face match: Confirms a live person and matches the selfie to the ID photo.
• NFC and age estimation: Reads ID chips and estimates age from a face image.
• AML and transaction monitoring: Screens sanctions and PEP lists and monitors payments.
• Wallet screening and KYB: Screens crypto wallets and verifies business entities.
• Workflow orchestrator: Combines modules into no-code onboarding flows via one API.

A Vietnamese fintech startup can launch KYC with liveness and AML screening on the free tier before scaling. A licensed digital asset platform can combine KYC with wallet screening and transaction monitoring. A cross-border marketplace can verify sellers and businesses from many countries.

Didit offers 500 full KYC verifications per month free, then 0.33 USD per full KYC bundle on pay-as-you-go, which it says is 3 to 5 times cheaper than incumbent vendors. It reports 99% of verifications completing in under 2 seconds and a 99.99% SLA. Modular per-check pricing lets small teams start without contracts.

Pay-per-check, developer-first identity APIs are lowering the cost of KYC for startups, crypto exchanges and marketplaces. In Southeast Asia, new licensing regimes for digital assets and payments are pushing smaller firms to adopt KYC, AML and wallet screening early.
