Shares a payout wallet with 25 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

EU VAT number validation (VIES) with predictable behavior for agents. Validates any EU VAT number against the European Commission's VIES service. Two modes: fast validation (may serve a cached result, labeled with its timestamp) and consultation-proof mode (always live, returns the official consultation number, requires requester identification). 'Not confirmed' does not imply the company is invalid. Machine-readable errors with per-member-state availability status.

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
3

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.

This payout wallet is shared: figures cover all 26 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
