Public Data Gateway

The gateway is a permissionless router that selects verified provider packages and returns a canonical Attested Data Response (ADR).

Selection rule (MVP)​

  1. Score (score_v2) descending
  2. Freshness penalty applied
  3. Verified signature + anchor + payload hash

Trust tier labeling​

Gateways MUST label responses with explicit tiers:

  • TIER_A_PROVIDER_SIGNED
  • TIER_B_ADAPTER_ATTRIBUTED

Multi-gateway preparation​

  • Gateways can register in GatewayRegistry and submit usage aggregates per epoch.
  • Usage is reported via EpochUsageRegistry for reward distribution.
  • Gateways MAY operate in EPOCH_BATCHED mode, where credits are settled per epoch and receipts include epochId + usageId.

Optional app discovery​

Gateways may expose app registry endpoints:

  • GET /v1/apps
  • GET /v1/apps/:appId

Disclaimers​

Gateway responses are verifiable but not guarantees of outcomes. Fees may be zero. No guarantees. Not investment advice.
