How this service works
Add-on, statistical strata: share of the last 5 years spent in each official band for this day-of-year, the percentile bands, and where the current reading falls. Backtestable, and stated as approximate. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.
Output
A JSON object containing: the strata object with 5-year same-season historical layer proportions, quantile breakpoints, and the current value's stratum placement; entity and signal identifiers; observed_at timestamp; provenance block with freshness, data lineage, and age; an offline-verifiable citation with Ed25519 signature and DID; and a record_hash for integrity verification. Includes a grade disclosure and scope statement clarifying this is observational, not predictive or advisory.
Example use cases
Seasonal percentile context for unemployment
“Pull the strata breakdown for US unemployment (signal_id: macro.unemployment, entity: us) — I want to see how the current reading compares to the same quarter over the past 5 years and which official stratum layer it falls in right now.”
Crypto spot stratum check for Bitcoin
“Where does Bitcoin's current spot price land in its historical seasonal stratum distribution? Use signal_id crypto.spot and entity btc — I need the quantile bands and the layer the current value falls into.”
Shipping disruption historical stratum analysis
“Check the statistical stratum profile for Hormuz shipping route disruption (signal_id: shipping.route-disruption, entity: hormuz) — show me the 5-year same-season layer proportions and tell me which stratum the current value is in.”
Technical details
Endpoint
GEThttps://aeml-x402.zeabur.app/gauge/strataWhen to prefer
Use this endpoint when you need seasonal statistical context for a signal — specifically, where the current value sits within its historical stratum distribution for the same season over the past 5 years. Prefer this over /gauge (full core) when you only need strata projection at lower cost ($0.03 vs full gauge price), and over /gauge/ruler when you want quantile-based stratum placement rather than official threshold distances. Best for backtestable, seasonal benchmarking of macro, crypto, hydrology, agriculture, or shipping signals.
Side effects
- 422 Unprocessable Entity if the requested signal_id has no strata definition (not all signals have official stratum bands)
- Missing or invalid signal_id / entity parameters return an error
- Stale data: freshness field may be 'stale' for low-cadence official signals (monthly/quarterly/annual); data_age_hours may be frozen if collector is down
- record_hash null if hashing is unavailable for a projected endpoint; recommend /gauge/verify for full core hash
- Unknown entity or signal_id returns 404 or error; consult /gauge/catalog for valid combinations
- Payment failure (x402): call requires $0.03 USDC on Base; unsigned or underpaid requests rejected
