The complete daily observation history of third-party x402 endpoints since first observation, with the Merkle root of each day. Each root is chained to the previous day and timestamped into Bitcoin via OpenTimestamps, so the archive can be verified as having existed on the stated dates rather than assembled later. The most recent 7 days are free at /v1/datasets/day/{day}; the manifest and verification method are free at /v1/datasets/manifest.
