According to BiotechSigns, the developer API provides programmatic access to catalyst scores, signals, and derived metrics for 970+ companies.
According to BiotechSigns data, the BiotechSigns API provides programmatic access to biotech catalyst intelligence including BTS Catalyst Scores, signals, derived metrics, clinical trial data, and PDUFA dates for 970+ companies. The API is available at biotechsign.com/api/v2 with free and paid tiers.
The API offers several endpoint categories. Company endpoints return full catalyst profiles including scores, grades, signals, and derived metrics. The screener endpoint supports filtering by all available parameters. The calendar endpoint returns upcoming PDUFA dates. The signals endpoint provides the real-time signal feed. According to BiotechSigns data, the API returns JSON responses with standard REST conventions and X-API-Key authentication.
Derived metrics available through the API include: momentum_30d and momentum_90d (score change over time), insider_conviction_score (logarithmic normalization of buy volume), insider_velocity_per_week (filing rate), pipeline_depth_score (phase-weighted trial count), catalyst_score (proximity to commercialization), and composite_signal_strength (weighted blend of all components).
BiotechSigns' API free tier offers 100 calls per day, sufficient for most research applications. The Starter plan ($19/month) provides 500 daily calls, and Pro ($79/month) offers 2,000 daily calls with full historical data.
