ClinicalTrials.gov Scraper | Sponsors & Research Sites
Pricing
from $2.00 / 1,000 delivered studies
Export ClinicalTrials.gov study records with sponsors, eligibility, outcomes, available contacts, complete nested locations and explicit source dates.
Optional ClinicalTrials.gov search or studies-API URL. Its query replaces the separate search filters. The study limit and safety settings still apply. No credentials or other hosts.
Stop after this many distinct study rows. This is separate from page size and request budget. A large accepted value does not guarantee that a run will finish within its time or charge limit.
Search diseases or conditions, for example type 2 diabetes. Can be combined with the other search fields.
Search other terms in registry records. Leave empty to omit this query.
Search an intervention, medicine, device or procedure reported in a study.
Search the registry by place, such as city, region, postal code or country. This filters studies; it does not remove other listed sites from a matching study.
Choose all study statuses or the recruiting and not-yet-recruiting study statuses. A study status does not imply the same status at each site.
Restrict study eligibility by sex, or leave unrestricted. This is registry eligibility data, not participant-level data.
Select any standard age buckets to match. An empty list leaves this filter unset. Manual age bounds are separate filters.
Optional nonnegative lower eligibility-age bound, expressed in the chosen lower-bound unit.
Unit for the lower age bound. Subyear units remain available.
Optional nonnegative upper eligibility-age bound, expressed in the chosen upper-bound unit. Reversed bounds must be corrected.
Unit for the upper age bound. It may differ from the lower-bound unit.
Enable to require studies that accept healthy volunteers. Leaving this off adds no healthy-volunteer restriction.
Choose one or more trial phases. Early Phase 1 uses phase0; notApplicable preserves the registry not-applicable category.
Select study categories, including patient registries and individual, intermediate-size or treatment expanded-access categories. An empty selection adds no type restriction.
Require posted results, require their absence, or leave unrestricted. This does not request extraction of results tables.
Filter for uploaded protocol, statistical-analysis-plan or informed-consent documents. Returned document metadata does not download attachment bytes.
Select reported sponsor or funder categories. This does not infer an organisation category from its name.
Optional from bound for study start, written YYYY-MM-DD. Source dates keep their published precision; do not enter a fabricated day into source output.
Optional through bound for study start, written YYYY-MM-DD. Source dates keep their published precision; do not enter a fabricated day into source output.
Optional from bound for primary completion, written YYYY-MM-DD. Source dates keep their published precision; do not enter a fabricated day into source output.
Optional through bound for primary completion, written YYYY-MM-DD. Source dates keep their published precision; do not enter a fabricated day into source output.
Optional from bound for study completion, written YYYY-MM-DD. Source dates keep their published precision; do not enter a fabricated day into source output.
Optional through bound for study completion, written YYYY-MM-DD. Source dates keep their published precision; do not enter a fabricated day into source output.
Optional from bound for first registration posting, written YYYY-MM-DD. Source dates keep their published precision; do not enter a fabricated day into source output.
Optional through bound for first registration posting, written YYYY-MM-DD. Source dates keep their published precision; do not enter a fabricated day into source output.
Optional from bound for first results posting, written YYYY-MM-DD. Source dates keep their published precision; do not enter a fabricated day into source output.
Optional through bound for first results posting, written YYYY-MM-DD. Source dates keep their published precision; do not enter a fabricated day into source output.
Optional from bound for latest study update posting, written YYYY-MM-DD. Source dates keep their published precision; do not enter a fabricated day into source output.
Optional through bound for latest study update posting, written YYYY-MM-DD. Source dates keep their published precision; do not enter a fabricated day into source output.
Search organisations named as lead sponsors or collaborators.
Search NCT identifiers or other registry-reported protocol identifiers.
Search a named study facility. Matching a facility must not discard the other locations of the study.
Enable to require the registry FDAAA results-submission violation annotation. This is not an independent legal compliance assessment.
Choose relevance or newest registrations first. Source sorting and any remaining continuation are recorded by the runtime; this is not a live change-monitoring service.
Maximum study count requested per API page. It is not the output limit; a source page may return fewer studies.
Limit all source-side transport attempts, including DNS resolution and the registry version request. Stop with explicit coverage status if another page would exceed the budget.
Time budget in seconds for this collection. The platform run timeout may be shorter; completed rows must not be labelled a complete source export after interruption.
Maximum accepted response bytes, with streaming and decoded-content checks. An oversized response is an explicit error, not silent field truncation.
