https://apiwitchcraft.duckdns.org/einvoicing/:countryShares a payout wallet with 19 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Surfaces VAT-compliance rules for B2B/B2G invoicing so agents and finance apps stay compliant before issuing. Pay per lookup in USDC on Base, no API key, instant JSON.

How often it was reachable when we probed it (weight 35%).
How quickly it answers when it is up — fast scores high (weight 20%).
Whether it serves over working TLS / https (weight 15%).
Whether the operator disclosed what it does — description, schema, identity (weight 15%).
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 58% — how much probe evidence backs this score. A thin history is flagged, not hidden.

This payout wallet is shared: figures cover all 20 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
