Stable delivery semantics
Signal dedupe keys make retries safe. Conflicting payloads stop instead of overwriting evidence.
Use free discovery endpoints, account-based subscriptions for volume, or x402 for no-account machine purchases.
Coverage and Proof are public. Paid endpoints use the same evidence model and preserve source timing in every result.

Signal dedupe keys make retries safe. Conflicting payloads stop instead of overwriting evidence.
Separate the underlying event, source publication, and SentientData retrieval times.
Public responses allow firm and official-record data only. Person-level enrichment never enters the shared cache.
x402 v2 uses Base USDC and standard PAYMENT-REQUIRED, PAYMENT-SIGNATURE, and PAYMENT-RESPONSE headers. Buyers should enforce price, network, resource, and spend limits in code before signing.
