Start with the index
GET /api/v1/topics lists published topics, sourcing counts, and links to readable and structured versions.
The same topics. Structured for agents.
Read the evidence,
carry its context.
The public API exposes the same published topics as our reading pages. No account or API key is required. Drafts are excluded from the API.
Follow a topic
GET /api/v1/topics/{slug} returns concepts, dated events, assertions, evidence, and source retrieval status.
Follow connected stories
GET /api/v1/stories lists reading guides. GET /api/v1/stories/{slug} includes the original topic assertions and evidence, with editorial questions separated from sourced statements.
Original documents
source.documents lists known publisher document links, formats, editions, locators, and access-check notes. These are outbound links, not hosted copies. A document link does not add an independent source or a human verification. Unknown file links are omitted.
Keep the sourcing labels intact
Reported does not mean editor-reviewed. Disputed claims retain the conflicting accounts. Preserve each assertion’s assessment and source links, and cite the topic’s readable URL.
Retrieval status describes whether a source was read; it does not establish that its claim is true. The response’s policy block explains the labels and the limits on source excerpts.
