Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k).

Look up completed diabetes studies
“I need to find completed clinical trials that focused on Type 2 diabetes — can you pull those from the U.S. federal database and give me a list with their titles and identifiers?”
Research trials by keyword
“Can you search the federal clinical trials database for studies involving 'mRNA vaccine' and show me what's currently active or recruiting? I'm trying to get an overview of where research stands right now.”
