Free tier gives counts, not the timeline
This device has 2 observations (2 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}.
Same model, in context
NVIDIA H200: 63 machines listed, 63 with a public price, median $3.685/GPU/h (P10–P90 $2.567–$5.626). One asking price says nothing about a market — read it against the distribution.
