Shares a payout wallet with 154 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Clinical trial search — find ClinicalTrials.gov studies by free text, condition, intervention, sponsor, recruitment status and phase, and get each study's NCT id, titles, status, phases, conditions, interventions, sponsor, start and completion dates, enrollment and whether results are posted. Use for drug development, medical research and patient-recruitment questions.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
100

How often it was reachable when we probed it (weight 35%).

Latency
100

How quickly it answers when it is up — fast scores high (weight 20%).

Security
100

Whether it serves over working TLS / https (weight 15%).

Transparency
61

Whether the operator disclosed what it does — description, schema, identity (weight 15%).

Activity
2

Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).

Confidence 44% — how much probe evidence backs this score. A thin history is flagged, not hidden.

This payout wallet is shared: figures cover all 190 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.

Linked by wallet — likely same operator
