Identity verification
built for El Salvador

Didit is infrastructure for identity and fraud, the platform we wished existed when we were building products ourselves: open, flexible, and developer-friendly, so it works as a real part of your stack instead of a black box you integrate around.

One API covers verifying people (KYC, know your customer), verifying businesses (KYB, know your business), screening crypto wallets (KYT, know your transaction), and monitoring transactions in real time, on a stack built to be:

• Fast, sub-2-second p99 on every session
• Reliable, in production with 1,500+ companies across 220+ countries
• Secure, SOC 2 Type 1, ISO 27001, GDPR-native, and formally attested by Spain's financial regulator as safer than verifying someone in person

The footprint underneath: 14,000+ document types in 48+ languages, 1,000+ data sources, and 200+ fraud signals on every session. The Didit infrastructure dynamically learns from every session and gets better every day.

Didit is the infrastructure layer for identity and fraud. One Application Programming Interface (API), 25+ composable modules across four product lines:

• User Verification (KYC, know your customer), Identity Document Verification, liveness, face match, Anti-Money Laundering (AML) screening, Internet Protocol (IP) analysis. $0.33 per full bundle.
• Business Verification (KYB, know your business), registry, Ultimate Beneficial Owner (UBO), officers, entity AML, plus a linked KYC session per UBO.
• Transaction Monitoring, real-time rule engine, case management, Suspicious Activity Report (SAR) workflow.
• Wallet Screening (KYT, know your transaction), on-chain wallet risk at $0.15 per check, or bring your own screening provider and run it inside Didit.

Compose any module into a workflow with the visual no-code builder, ship in 5 minutes, 500 verifications free every month, forever.

Most identity vendors sell one slice, a KYC check, an Anti-Money Laundering (AML) list, a wallet screen. Didit ships the infrastructure underneath all of them, and the gap shows up on six axes:

• Pricing. Public price on every module, $0.33 for a full KYC, 500 verifications free every month, no minimums, no contracts. Single-product vendors hide six-figure minimums behind a sales call.
• Access. Sandbox in one click, self-serve from day one, production keys on signup. Single-product vendors gate the sandbox behind a contract, months to evaluate.
• Developer experience. Public docs, a Model Context Protocol (MCP) server for Claude Code and Cursor, and native Software Development Kits (SDKs) for Web, iOS, Android, React Native, and Flutter. Integrate in 5 minutes with an AI agent or in a working afternoon by hand.
• User experience. Highest pass rates in the market, sub-2-second end-to-end inference, country-specialised capture flows, 48+ languages out of the box.
• Flexibility. One /v3/ Application Programming Interface (API) composes 25+ modules across KYC, Know Your Business (KYB), Transaction Monitoring, and Wallet Screening (KYT, know your transaction). A KYB session spawns a linked KYC for every Ultimate Beneficial Owner (UBO); a flagged transaction spawns a step-up KYC remediation, same session, same webhook contract, same audit trail. Single-product vendors sell one shape of KYC and stop there.
• AI-era fraud. 200+ real-time fraud signals scored on every session, deepfake, injection, synthetic-ID, document forgery, face-morph, device intelligence, replay. Single-product vendors treat deepfake and injection detection as roadmap items, not defaults.

Common in fintech and crypto, the same architecture fits marketplaces, iGaming, mobility, and any vertical where you need to know who someone is and what they are doing.

Four authorities sit on top of every Salvadoran identity-verification flow:

• Superintendencia del Sistema Financiero (SSF), sets KYC onboarding requirements for banks, cooperativas, and fintech lenders.
• Unidad de Investigación Financiera (UIF-FGR), El Salvador's Financial Intelligence Unit. Receives Reportes de Operaciones Sospechosas under Decreto 498/1998 (Ley Contra el Lavado de Dinero y de Activos).
• Banco Central de Reserva (BCR), oversees the payment system and electronic-money operators, including guidance on Bitcoin operations under Decreto Legislativo 57/2021 (Ley Bitcoin).
• Registro Nacional de las Personas Naturales (RNPN), civil-registry authority that issues the DUI and underpins the slv_dui database validation.

Didit ships the hosted flow + audit log + watchlist coverage to satisfy all four at the same time, same POST /v3/session/ workflow, same JSON report, same SOC 2 Type 1 + ISO/IEC 27001 evidence pack.

Yes, via the `slv_dui` Database Validation service (POST /v3/database-validation/):

• `slv_dui`, hits the Registro Nacional de las Personas Naturales (RNPN) directly. $0.20 per successful query, no end-user consent required. Inputs: document_number (exactly 9 digits, no hyphens) + date_of_birth. Returns identification_number, full_name.

Yes. Decreto Legislativo 57/2021 (Ley Bitcoin) made Bitcoin legal tender and created a new class of regulated service provider in El Salvador, Bitcoin wallet operators, exchanges, and payment processors, all subject to AML/CFT obligations under the existing Decreto 498/1998 (Ley Contra el Lavado).

Didit covers the full stack on one workflow:

• Identity Document Verification + Passive Liveness + Face Match 1:1 for the user-onboarding check.
• `slv_dui` Database Validation against RNPN, the authoritative source regulators expect.
• AML Screening ($0.20 per check) against the global pool plus Salvadoran regulatory watchlists (UIF-FGR lists, SSF sanctions, Ethics Tribunal, Crime Stoppers).
• Wallet Screening (KYT) at $0.15 per check for on-chain Bitcoin wallet risk scoring.
• Ongoing AML monitoring ($0.07 per user / year) for the Ley Contra el Lavado periodic-review obligation.

5 minutes to a working sandbox, a weekend to a production flow.

• Sign up at business.didit.me, grab an API key, call POST /v3/session/ with a workflow_id that wires ID Verification + Passive Liveness + Face Match + AML + RNPN database, done.
• AI-agent path: paste the integration prompt at docs.didit.me/integration/integration-prompt into Claude Code, Cursor, Codex, Devin, Aider, or Replit Agent. The agent provisions the application, builds the workflow, wires the webhook, and runs a smoke test.
• Five SDKs share the same session model: Web, iOS, Android, React Native, Flutter.

The first 500 verifications every month are free, forever, pilot the full El Salvador stack at zero cost before flipping production traffic.

Salvadoran Spanish, auto-detected from the user's browser or device locale. The hosted UI ships in 48+ languages; Salvadoran users land on the Spanish flow by default. English is also live on the same flow for cross-border or expat users.

The document-recognition layer is decoupled from the UI layer, capture works in any language, and the admin console can be set independently to whichever language your compliance team prefers.

Per-module public pricing, pay only for what runs on the session:

• ID Verification, $0.15 per document check.
• Passive Liveness, $0.10. Active Liveness, $0.15.
• Face Match 1:1, $0.05. Face Search 1:N, free.
• AML Screening, $0.20 per check. Ongoing AML, $0.07 per user / year.
• `slv_dui` (RNPN civil registry), $0.20 per successful query.
• Wallet Screening (KYT), $0.15 per check for Bitcoin wallet risk.

The full KYC bundle (Identity + Passive Liveness + Face Match + IP Analysis) is `$0.33`, same anchor price worldwide. 500 verifications free every month, no credit card. Volume discounts auto-apply above the free tier.
