  "description": "A repeated measurement of the whole public x402 service economy, taken from the Coinbase CDP Bazaar discovery API. Every reading counts the same population the same way, so the numbers are comparable across dates. Started 2026-07-24 and refreshed on a session cadence.",

    "population": "Only listings priced in Base-mainnet USDC at or under $100 are counted. The rest quote other chains or junk prices (one listing asks ten billion dollars).",
    "multi_price": "A listing quoting several USDC prices is counted at its lowest price, which is the conservative choice.",
    "revenue": "Estimated as price x l30DaysTotalCalls. The call counts are Coinbase's own and their counting rule is undocumented, so these are its numbers reported faithfully, not ours.",
    "window": "Every call and volume figure is a rolling 30-day window ending at the pull time, not a calendar month.",
    "timestamp_precision": "Only the newest reading carries an exact pull time. Earlier ones are recorded to the UTC date and the session that took them, which is the honest resolution of what was logged at the time.",
    "known_wobble": "The counted-listing figure moves by roughly plus or minus 1 percent between consecutive pulls hours apart. That is variance on the API side, not supply changing. Do not read a listing-count difference between two readings as growth or decline."
