Free tier gives counts, not the timeline

This device has 1 observations (1 within the last 90 days, 0 older). The individual records and the full timeline are the paid tier — that is where duplicate-pledge and default-history checks live. See pricing.

Paid deliverables

Verification report (serial number + ed25519 signature + content hash, $2) — GET /v1/report/{cvin}. If a device has no real external observation, the report is issued free and clearly marked demo_report.

Record contents are stored in Chinese and rendered on the Chinese page, which is authoritative for record text. Machine-readable: GET /v1/resolve/{cvin}.
