How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

Output

Returns a JSON object with total match count, search term echoed back, data source attribution, and an array of trial objects. Each trial includes: NCT ID, direct ClinicalTrials.gov link, title, current status, phase(s), sponsoring organization, medical conditions studied, interventions tested, start date, expected end date, participant count, and countries where the trial runs.

Example use cases

Recruiting trials for rare disease

“Find me all currently recruiting clinical trials for Duchenne muscular dystrophy — I need the trial titles, NCT IDs, phases, and which sponsors are running them.”

Drug-specific trial pipeline research

“Search for clinical trials testing tirzepatide — show me up to 50 results including their status, what conditions they're targeting, and expected end dates.”

Competitive pharma sponsor analysis

“Look up all clinical trials sponsored by Pfizer — I want to see their active studies, what phases they're in, and what diseases they're investigating.”

Technical details

Endpoint

POSThttps://api.vextorium.com/v1/clinical-trials?utm_source=zero.xyz

When to prefer

Use this endpoint when you need structured, queryable clinical trial data from ClinicalTrials.gov without building a direct NIH API integration. It is especially useful for agents doing medical research, competitive pharmaceutical intelligence, or patient-facing trial matching, and when you need recruiting trials by default with clean structured output. Prefer this over raw ClinicalTrials.gov API access when you need normalized, ready-to-use JSON with enrollment and country data already parsed.

Side effects

Empty results if search term is too specific or misspelled
Null fields for trials missing optional metadata (phases, countries, expected_end)
Status filter returning no results if no trials match the requested status
Rate limiting or payment failure if USDC balance is insufficient
Malformed search string causing backend query failure
