DeepInquiry on AWS Data Exchange

What the API returns

Every response returns a verified fact plus its full provenance record. DeepInquiry only ships facts that pass a source-independence check — two or more structurally independent sources per fact, with syndicated duplicates and mirror sites excluded before counting. See our verification methodology for how independence is graded.

Each fact response carries:

• fact_text — the verified claim, as written
• verification_tier — gold, silver, or bronze, based on the evidence strength
• independence_score — a 0.0–1.0 measure of how structurally distinct the corroborating sources are
• cluster_count — number of independent source clusters supporting the fact
• sources — URL, publisher, cluster ID, and domain class for every corroborating source
• category, era, region — classification tags
• citogenesis_flags — empty on clean facts; populated when the source cluster shows signs of copying from a single seed

Subscription tiers

Contracts are monthly and auto-renew. Rate limits are enforced by our backend. If your workload needs a longer term or a custom volume, reach out at aws-support@deepinquiry.ai.

Getting started

1. Subscribe to DeepInquiry — Verified Facts API on AWS Data Exchange. Choose the tier that matches your expected volume.
2. AWS provisions a subscription-specific endpoint under the AWS Data Exchange domain. That endpoint proxies to our backend and injects your subscriber credentials automatically. You do not need a separate DeepInquiry API key.
3. Call the endpoint from your AWS account with SigV4 authentication (any AWS SDK handles this). The response schema matches the sample above.
4. Track your usage in the AWS Data Exchange console. Overage on the monthly cap returns HTTP 429; upgrade to the next tier for higher volume.

OpenAPI specification

The full OpenAPI 3.0 specification for this API is attached to the Data Exchange product listing and downloadable from the AWS Data Exchange console once you have subscribed. It documents every endpoint, query parameter, and response field.

Data update frequency

The corpus grows continuously. New facts pass through our ingest and verification pipeline and land in the API roughly every 15 minutes. Individual facts do not change once verified; the API always returns the current corpus state. No revision or snapshot schedule is required.

What DeepInquiry is not

• Not a search API against the open web. DeepInquiry ships a curated, pre-verified corpus.
• Not a fact-check-on-demand service. Every fact is verified before it enters the corpus, not on request.
• Not a single-source aggregator. Claims with only one source or without cross-corroboration are not admitted to the corpus.
