EYEWITNESS chain verified

Why this exists

Built for serious work, not vibes.

Two halves of the same problem: making 1,400 years of scholarship findable, and giving you the chain back to the source every time.

01 / 02

Semantic search across the full classical canon.

One request returns ranked passages with source attribution, era tagging, chain strength, and pre-flagged scholarly conflicts. No more stitching together translations by hand.

Embedding-based retrieval, tuned for Arabic-derived corpora
Chain-of-narration scoring built into every result
Conflict detection across competing primary accounts

# Semantic search across the full corpus
curl -X POST https://islamiccorpus.com/query \
  -H "X-API-Key: your_key" \
  -H "Content-Type: application/json" \
  -d '{"q": "Khalid ibn Walid at Yarmouk", "n": 5}'

# → ranked chunks, source, era, chain_strength, score
# Top result: Al-Tabari Vol 12 (0.847) — eyewitness

02 / 02

Structured research briefs in one call.

The /research endpoint composes a multi-query context packet — primary accounts, character context, religious context, and source conflicts — for any figure × event × era combination.

One endpoint replaces six separate retrieval calls
738 figures pre-mapped in the knowledge graph
Sensitivity tiers and scholarly debates surfaced automatically

# Full research brief for a figure + event
curl -X POST https://islamiccorpus.com/research \
  -H "X-API-Key: your_key" \
  -H "Content-Type: application/json" \
  -d '{"figure": "Saladin",
       "event":  "Fall of Jerusalem",
       "era":    "crusades"}'

# → primary accounts + character context
# → religious context + pre-flagged conflicts

Endpoints

Four ways to query the corpus.

A small, sharp API surface — semantic, structured, graph, and manifest.

POST /query

Semantic search. Returns ranked chunks with source attribution, chain strength, and conflict flags.

POST /research

Structured research brief. Multi-query context packet for a figure + event — primary accounts, character context, pre-flagged conflicts. The power endpoint.

GET /figure/{name}

Knowledge graph entry. Sensitivity tier, relationships, scholarly debates, lineage, source coverage count.

GET /sources

Full source manifest. 216 sources with chunk counts, authentication tier, and chain strength.
