Qualifying teams can test real workloads against the production FactLens API, measure evidence quality and latency, and prove an integration before moving to ongoing paid usage.
Production API access
Evaluate the same verification API used for ongoing workloads.
Real integration testing
Measure request patterns, evidence quality, latency, retries, and the end-user experience.
Prove the integration with meaningful usage.
The program is designed for projects that need enough volume to validate a product, workflow, study, classroom deployment, newsroom tool, or public-facing service.
Build against production
Test structured verdicts, citations, retries, and the end-user experience with the real API.
Measure real workloads
Understand latency, request patterns, evidence quality, and the economics of your intended deployment.
Scale without rework
Keep the same integration when approved credits finish and move to straightforward usage-based access.
Clear use cases with a path to deployment.
Startups, researchers, educators, journalists, student builders, public-interest teams, and other responsible projects with a concrete use case are welcome to apply.
Products and startups
Teams evaluating FactLens for a real customer, product, moderation, research, or internal verification workflow.
Research, education, and journalism
Researchers, educators, newsrooms, and student builders with concrete projects and measurable evaluation goals.
Public-interest projects
Civic and responsible applications where evidence-backed verification supports a real service or public-facing workflow.

Apply for up to $1,000 in Free API Credits.
The Free API Credits program is for teams that need meaningful usage to prove an evidence-backed FactLens integration before committing to ongoing paid capacity.
Suitable applications include products, research studies, classrooms, journalism tools, student builds, civic projects, and other responsible services with a clear fact-checking use case.
Tell us what you are building, who will use it, where FactLens appears in the workflow, and the request volume you realistically expect during evaluation.
If approved, projects may receive up to $1,000 in credits for the production FactLens API so you can test structured verdicts, citations, evidence quality, retries, latency, and your end-user experience.
After submission, the application is reviewed for suitability, implementation readiness, expected workload, and current program capacity; the decision is sent to the email you provide.
