How this service works
Forecast Integrity Audit. Integrity receipt for sealed five-minute forecast history: cutoff timing, feature hashes, settlement sources, and agent prediction coverage, with Brier quality disclosed separately. A large sample does not turn a weak score into demonstrated edge. Audit evidence only, not a forecast or trading signal.
Output
A structured integrity receipt containing: cutoff timing for each round, feature hashes attesting to sealed inputs, settlement sources used for scoring, agent prediction coverage statistics, and a separately disclosed Brier quality score. The receipt is audit evidence only — it does not constitute a forecast or trading signal.
Example use cases
Pre-purchase forecast track record audit
“Before I subscribe to LUMI's forecast service, can you pull an integrity receipt for the lumi agent covering the last 100 rounds? I want to see the Brier quality score and confirm the feature hashes look consistent.”
Consensus agent prediction coverage check
“Run a forecast integrity audit on the consensus agent for the last 10 rounds and tell me what the prediction coverage looks like and whether the settlement sources match up.”
Regulatory evidence of sealed forecast history
“I need tamper-evident audit evidence for the tenna agent's forecast history — pull an integrity receipt for the last 50 rounds showing cutoff timing and feature hashes so I can document it for compliance.”
Technical details
Endpoint
POSThttps://app.tenna.ai/api/x402/lumi/forecast_integrity_receiptWhen to prefer
Use this endpoint when you need cryptographic audit evidence of a forecast agent's historical integrity — verifying that inputs were sealed before settlement, checking Brier quality scores, or producing compliance documentation. Prefer this over simply reading agent outputs when you need tamper-evident proof rather than live predictions. Not appropriate when you want an actual forecast or trading signal.
