Urd Atlas
Daily, deterministic network-state reference data for Bitcoin, Ethereum, Arbitrum and Base — one joinable row per chain and date.
Each chain is evaluated against its own recent history. Stronger labels require corroborating demand, friction and capacity evidence; weak evidence is withheld rather than forced into a dramatic state. Every row carries its Evidence score, methodology version and provenance.
What Urd Atlas actually gives you
Four JSON files. One daily observation.
The classification is deliberately compact, but the evidence behind it stays inspectable. These are the four actual published layers for the selected chain and date — not synthetic previews.
How the latest Bitcoin state is assembled
The latest Bitcoin observation is CHEAP for 29 Aug 2026. The current low-friction evidence meets the profile-specific CHEAP rule relative to this chain’s recent history. The 91% Evidence score reflects strong evidence support from data quality and label-specific evidence. It is an uncalibrated evidence-strength quantity, not the probability that the label is correct.
How to read it: classifier bands and trend are the regime evidence, while the numeric axis values are smoothed scorecard displays. Stronger named states require corroborating evidence, and constant, near-constant or insufficient distributions cannot manufacture HIGH/LOW bands.
Inspect the schema first. Subscribe only when it fits your workflow.
Single Chain is $49 a month for one chain and Research is $149 a month for all four. The public sample lets you check the schema and the date + chain join before paying for recurring delivery.
Validation, source checks, provenance and methodology are public so the operational contract can be audited before you rely on it.
