It holds the raw output of two scans that\nrun every day, plus every script that produced it, in the same directory.\n\nThe first scan reads both public x402 service directories, Coinbase's and the PayAI facilitator's,\nevery day at 04:40 UTC. Each Coinbase entry carries a demand measurement: calls in the last 30\ndays, distinct paying wallets in the last 30 days, and the timestamp of the last call. The raw CSV\nof each day is kept for sixty days and the derived daily figures for good.\n\nThe second scan reads every USDC transfer into the receiving address of the Conway Automaton\nproject, 0x21DD37E3E4eA6CCC0a5C98A4944702eDE6E7Be10, on Base, every day at 05:00 UTC. The first\nfull pass covered 1 January to 20 September 2026 and read 9,027 transfer events over 5,652\neth_getLogs calls of 2,000 blocks each, which takes about thirty minutes against the public RPC.\nEvery day since is scanned forward from the newest block already held. The columns are block,\ntimestamp_utc, from, usdc and tx_hash.\n\nTwo limits belong in the opening, because somebody reusing this will otherwise state more than the\ndata supports. First, the transfer file shows money arriving at one address and nothing else:\nwhether a wallet is a person, an unattended runtime or a retry of the same failure is not in the\ndata, and the recent average of about two transfers per wallet fits the upstream runtime's retry\nbehaviour rather than two purchase decisions. Second, Coinbase fills its demand fields in late, so\nevery total taken from the directory is a floor and not a count: on 20 September 2026 the largest\nservice in the whole directory was listed with empty demand fields and appeared the next day with\n346,869 calls against the same trailing 30 days.\n\nOne practical trap is worth naming in the opening: the public Base RPC answers Python's default\nUser-Agent with 403, and setting any User-Agent header of your own fixes it.\n\nWrite the opening section of the README. 150 words maximum. Plain prose in two or three\nparagraphs, no heading, no bullet lists.\n\nThe reader is a researcher or developer who has just landed in the directory from a link and is\ndeciding in thirty seconds whether this data answers their question.
