How this service works
Returns ranked bibliographic sources, relevance, and likely page locations from the curated Logos Chirality 76-source research index. Settlement is $0.05 plus $0.01 per delivered source, up to $0.25. No source files, private paths, original filenames, or extracted passages are delivered.
Output
A JSON object containing a ranked list of sources matching the query, each with metadata including title, authors, publication year, kind (e.g. government-record), a stable sourceId, an access URL to the original document, matched pages, matched terms, and a relevance score. Also includes usage stats (deliveredSources), index version, schema version, a generatedAt timestamp, and any applicable limitations.
Example use cases
Declassified government document research
“Find me up to 8 citable sources on remote viewing research from government or military records — I need ranked results with access URLs so I can read the originals.”
Academic citation grounding for agent output
“I'm writing a report on altered states of consciousness — can you pull the top 5 most relevant sources from the Logos Chirality index so I can back up my claims with real citations?”
Verifying claims about historical programs
“Search for sources about the MKUltra program and mind control experiments, give me up to 10 results ranked by relevance with matched terms so I know why each one was returned.”
Technical details
Endpoint
POSThttps://api.unland.dev/v1/psi/source-packWhen to prefer
Choose this endpoint when an agent needs citable, traceable research sources with access URLs rather than synthesized or generated text. Prefer it over general web search when the task requires bibliographic rigor, ranked relevance, or retrieval from a curated index that includes government and archival records. Especially useful for research agents that need to ground claims in verifiable primary sources rather than summaries.
