Introducing the Sonar Marketplace: Unified access to third-party risk data

If you work in fraud prevention, you know the pain of managing multiple risk data vendors.Each new provider means another contract, another integration, and another set of dashboards to maintain. It slows down your team, drives up costs, and leaves gaps that fraudsters take advantage of.

Today we’re launching the Sonar Marketplace, enabling organizations to access unified fraud data and pull third-party risk data from multiple trusted providers through a single API.

Instead of juggling vendor integrations and procurement cycles, you can plug into the Marketplace once and start using new risk and fraud signals right away. Teams can test new vendor data in a sandbox before deployment, benchmark sources side by side, and activate new data without engineering or procurement delays.

Our goal is to remove any unnecessary barriers between fraud operations teams and the data they need to stay ahead of financial crime

Leveraging the Sonar Marketplace

Sonar operates as an inquiry and response network. Any organization can call the Sonar API with basic identifiers for a person or business, such as a name, email, phone number, or business detail, and receive a structured risk response based on Sonar’s cross-industry intelligence.

Our Marketplace enables you to further enrich that entity or counterparty with data from trusted third-party vendors. You choose the providers that match your use case, and Sonar resolves the entity, gathers insights from Sonar, Sardine, and your selected vendors, and returns a single, standardized response of vendor-agnostic fraud data.

Current Marketplace coverage includes:

  • Email intelligence
  • Bank account intelligence
  • Global sanctions data
  • Phone intelligence
  • Crypto monitoring insights

Sonar members and consortium participants are already using this third-party data to improve onboarding verification and counterparty screening.

Data vendors: Why join the Sonar Marketplace

Joining the Sonar Marketplace enables you to sell your data to a wide network of banks, fintechs, and processors without long sales cycles or multiple implementations.

Once you are connected to Sonar, any participant can ingest your data through the fraud data API, and you get to keep 100% of the revenue from those API calls. It’s a scalable, low-cost way to reach more customers and grow your revenue without the extra operational and technical overhead.

FAQs

What is a fraud data API?

A fraud data API is a single endpoint that returns identity, device, behavior, sanctions, and consortium risk signals on a customer or transaction. The Sonar Marketplace is Sardine's vendor-agnostic implementation.

How does the Sonar Marketplace differ from a single-vendor fraud API?

Single-vendor APIs lock you to one signal source. The Sonar Marketplace federates signals from dozens of best-in-class vendors behind one normalized response, so you can swap or add vendors without rewriting your integration.

What latency does the Sonar Marketplace add?

Sub-50 milliseconds at the 95th percentile. The federation layer is co-located with the signal sources so the total round trip stays inside the latency budget of a real-time fraud decision.

Is the Sonar Marketplace compliant with model risk and audit requirements?

Yes. Every signal ships with provenance metadata, version history, and SR 11-7 / NIST AI RMF documentation. Auditors get a single source for every decision factor.

How do I join the Sonar Marketplace as a data vendor?

Apply at joinsonar.com. Vendors are vetted for signal quality, latency, and compliance before going live to Sonar customers. Once approved, your signals are delivered through Sardine's normalized API with no extra integration work for the buyer.
