Caveats

Things to know before drawing strong conclusions

· Calls and volume are 30-day cumulative figures from the source facilitator. Daily breakdowns are not yet available — see /methodology.
· Volume = price × calls. If the server publishes multiple price tiers, only the first accepts[] entry is used.
· "Last call" is what the source last reported, refreshed every 60 seconds.
