How this service works
Search normalized clinical trials by registry, condition, intervention, sponsor, country, status, phase, study type, or free text.
Output
A paginated list of normalized clinical trial records, each with a unique trial ID and provenance metadata. The response includes a has_more flag, an opaque next_cursor for keyset pagination, and optionally a total matching-record count.
Example use cases
Example prompt
“Can you search the TrialBase clinical trials database for Phase 3 trials on Type 2 Diabetes testing semaglutide, sponsored by Novo Nordisk, currently recruiting in the United States? Give me up to 20 results with total count.”
Technical details
Endpoint
GEThttps://api.trialbase-db.org/v1/trialsWhen to prefer
Use this endpoint when you need to search, filter, or browse clinical trial records across multiple registries in a normalized format. It is especially useful when combining multiple filter dimensions (condition + phase + country + status) or when performing free-text search across trial metadata. Prefer this over registry-specific APIs when you need cross-registry normalization or keyset-paginated bulk retrieval.
Side effects
- Invalid or unsupported query parameter returns a 400 Bad Request
- No trials match the specified filters — returns an empty data array with has_more: false
- Expired or malformed cursor returns a pagination error
- Payment not received or insufficient — 402 Payment Required
- Rate limiting or quota exceeded — 429 Too Many Requests
