api.duoleads.com
https://api.duoleads.com/v1/num/wordsShares a payout wallet with 32 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.
Spell a number out in words in English, Dutch, German, French, Spanish, Italian, Portuguese, Polish, Russian, Turkish, Swedish or Japanese, in cardinal, currency or year form, and ordinal form in English, Dutch, German and French. Currency form applies the correct grammatical agreement and the right minor-unit name and count for the supplied ISO 4217 code. Handles negatives and values up to 10^15.

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 100% — how much probe evidence backs this score. A thin history is flagged, not hidden.
See the scoring methodology for exactly how each number is computed.

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.
