        "Coinbase's public discovery API reported 96,113 indexed resources on October 29, 2026, and Coinbase's seller documentation describes the Bazaar as listing more than 23,000. A resource is indexed after its first payment settles through the CDP facilitator, so each entry proves at least one payment, not a customer.",
        "Each listing carries l30DaysUniquePayers and l30DaysTotalCalls: the facilitator's count of distinct paying wallets and of calls in the last 30 days. Those two numbers are what separate usage from presence."

      "paragraphs": [
        "When Ontario pulled the full index on October 17, 2026 (46,420 resources at the time), 74% of resources had one or two unique payers in the previous 30 days. The first paid call that triggers indexing is usually the seller's own, so a count of one or two mostly records sellers paying themselves to get listed. About 20,000 of those routes sat on a single host.",
        "The index has grown since, and Ontario has not repeated the full pull, so the share may have moved. The pattern it describes, a long tail of listings with no outside buyer, is visible in the per-listing counters on any page of the index."

      "paragraphs": [
        "Repeat demand, where calls are many times the number of payers, concentrated in a few categories in that pull: LLM chat and inference, web search and page reading, and on-chain data. Two web-search listings read on October 29, 2026 show the shape: one with 96 payers and 8,945 calls in 30 days, another with 165 payers and 30,768 calls.",
        "Calls per payer is the more useful measure. A resource with 100 payers and 100 calls was tried once by each; one with 165 payers and 30,768 calls is being used. For anyone building for agents, that ratio separates real usage from listing noise."
