- General information, not legal, financial or tax advice.
- Provider rates are a hand-keyed snapshot, several via a secondary report. Treat verdicts as a prompt to ask your provider, not a finding.
- Requests over 20 kB are rejected. Nothing is stored.
/data/rates.json has the same rate data as plain JSON.
