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

Current and resolved US drug shortages from openFDA, newest update first. Optional `?company=Pfizer` narrows to one manufacturer (omit for market-wide); `?limit=` (max 100). Each carries the generic name, company, status, therapeutic category, dosage form, presentation, posting/update dates, and reason. A supply-side catalyst for generic makers. From x402stock

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
99

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

Latency
97

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
1

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 100% — how much probe evidence backs this score. A thin history is flagged, not hidden.

Operator context is derived from public RDAP/TLS records and unverified. Company and country are only available for endpoints that publish them (an OV/EV TLS certificate or a non-redacted domain record); most endpoints are CDN-fronted and disclose neither.

Payout address changed 3 times, last on 8/24/2026

  • 0xc4d3…4dab → 0xfdb4…ed03 (base) · 8/24/2026

A changed payout address is worth a second look — it can be routine, but it is also how a hijacked listing redirects funds.

This payout wallet is shared: figures cover all 155 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
