Free public data · no key for eight MCP tools
Put the live funding-stress regime inside your agent.
One hosted MCP URL gives an agent the conclusion, the precedent, the freshness of the evidence, and compact oil/FX/material transmission context. Eight tools are public; five additional tools appear with a bearer token. The historical diagnostic always carries its served status plus validated-backtest and real-money eligibility flags. Or use REST when you only need JSON.

REST · smallest assembled read
Fetch the gauge
A compact current contract for dashboards, alerts and risk pipelines. It is assembled from the board and can be slower on a cold rebuild; treat timeout or error as unavailable, never as calm.

Inspect the v2 coverage receipt
Snapshot captured 9 August 2026 at 14:36 UTC: 10 packs, 87,000 canonical observations across 28 role series and 220 forward validation records. US-USD is VALIDATING, 9 packs are REFERENCE, none is SUPPORTED or evidence-eligible, and Global Tide is UNAVAILABLE. Query the endpoint for the current accrued count.

REST · cross-market context
Trace upstream cash pressure
Chartless Oil × Funding includes Ballast's bounded WTI/Henry Hub cash-displacement ledger plus live Cushing and Brent−WTI observations separated from dated capacity and chokepoint references; Estuary adds FX/material pathways. Observations, derivations, holdout evidence and scenarios stay separate.
