Shares a payout wallet with 1,051 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Weekly digest of rail economics for x402/MPP payments: per-rail transfer fees, facilitator bps, live Base gas, last-week settlement volume by rail/facilitator/product, sampled transfer gas, and an LLM-composed signal. Cache is 7 days so each paid call is a fresh weekly read.

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

Availability: 100
Latency: 100
Security: 100
Transparency: 67
Activity: 0

Confidence 96% — how much probe evidence backs this score. A thin history is flagged, not hidden.

This payout wallet is shared: figures cover all 1,052 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

On-chain agent identity and the x402 endpoint that shares its settlement wallet.
