An API for verified evidence.
Full API documentation is in private preview alongside the SDK. We're finalizing endpoint contracts with design partners before publishing the developer guide. Request access to receive an API key, the OpenAPI spec, and integration support.
What the API will cover
Evidence verification
Submit a claim or LLM output; receive a calibrated verdict with source citations and an immutable audit ID.
Entity retrieval
Look up findings about a drug, condition, biomarker, or guideline — every result carries source provenance.
Per-sentence grounding
Score generated text sentence-by-sentence against verified findings; flag unsupported assertions.
Domain-specific endpoints
Specialized routes for FHIR prior authorization, biomarker validation, drug interactions, variant classification, and more.
Audit trail & provenance lineage
Cryptographically chained audit records for every API call, plus OLMoTrace-style per-claim provenance lineage — source documents, finding derivation chain, confidence at each stage, and cross-validation count. Exportable for regulatory review.
Citation retraction monitoring
Daily checks across PubMed, CrossRef, and Retraction Watch. Retraction events cascade automatically to dependent findings within 48 hours — downstream findings derived from a retracted source are flagged and down-weighted. Retraction status is a first-class property on every finding.
Webhooks & batch
Long-running verifications and batch endpoints for evidence reviews, plus webhook callbacks for completion.
