Endpoint
GEThttps://x402helper.xyz/89e509/trials/study?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need programmatic, pay-per-call access to ClinicalTrials.gov study records by NCT ID and are operating in an x402 USDC micropayment environment. Prefer this over direct ClinicalTrials.gov API calls when you need a metered, agent-friendly interface with x402 payment rails built in.
Side effects
- Invalid or non-existent NCT ID returns empty or error result
- Missing required 'input' field returns schema validation error
- Payment failure via x402 results in 402 Payment Required response before data is returned
- Network timeout if ClinicalTrials.gov upstream is slow
