STEP 01
Ingest Sources
PDF and URL content enters through API routes with parsing, cleanup, and source metadata.
System Design
Reusable RAG Delivery Foundation
A compact RAG architecture focused on the pieces that matter after launch: source ingestion, retrieval boundaries, cited answers, and observable failure states.
STEP 02
Chunk + Embed
Text is chunked for retrieval quality, then embedded with OpenAI embeddings.
STEP 03
Retrieve Evidence
Pinecone session namespaces return top context chunks for each user query.
STEP 04
Stream Answer
Chat responses stream back with citations, source tags, and fallback behavior when evidence is thin.
Rate Limits
Per-endpoint throttling controls abuse and API spend.
Request IDs
Every response includes X-Request-Id for incident tracing.
Metrics Snapshots
Runtime counters track success/error mix and average latency.
