Fact

The unit of retrieval. A fact is a structured claim with a confidence score, a decay class, a source URL, a rerank score, and a firewall verdict. It is not a snippet, not a chunk, and not a paraphrased summary. Every fact came out of the structured-extract step with attribution attached. Facts are cacheable on their own, separate from the query that produced them. See Fact Cache.

Depth

An integer (1, 2, or 3) that tells the engine how hard to look. Depth 1 is a single pass. Depth 2 adds a reflection loop. Depth 3 streams the loop and lets a stopping AI judge saturation, then synthesizes. Pick by question shape, not vendor preference. See Depths.

Pipeline

Seven layers run on every depth: cache check, query decompose, search fan-out, structured extract, firewall, rerank, fact deposit. Depth changes how many times the loop runs, not which layers run. Splitting the pipeline lets each layer fail independently and lets operators reason about cost, latency, and integrity per layer instead of for a black box. See Pipeline.

Fact Cache

Per-tenant durable storage for facts the pipeline has already extracted. The cache compounds with every query a tenant runs; deeper queries seed the cache faster. Decay classes (fast, normal, slow, frozen) control how long a fact remains useful before re-extraction. The cache is the single most useful thing for an agent loop and the single most expensive thing to copy across vendors. See Fact Cache.

Firewall

Inspects every fact candidate before it reaches rerank, the cache, or the calling agent. Verdicts: quarantine, surface-with-warning, drop. The firewall is what makes the cache safe to compound. Without it, a single poisoned page can hijack any agent that retrieves from it. See Firewall.

Auth modes

Four modes at one endpoint: API key for the simplest case, x402 for machine-to-machine commerce, MPP for multi-party flows, and TrueCom for signed-receipt agentic commerce. Pick by integration shape; the response envelope is the same. See Auth and payment.

Where DeepTap fits

DeepTap is the retrieval layer for agents. It composes with but does not require the rest of the Good Ventures Lab portfolio. Veritize verifies the agent's output after the fact. R1 agents call DeepTap as their retrieval layer. RelayOne sits in front when an enterprise needs identity-scoped policy. TrueCom ships a signed receipt for every retrieval. The graceful-degradation principle holds at every seam: a DeepTap deployment without RelayOne still has auth; without Veritize still has firewall; without R1 still has retrieval; without TrueCom still has receipts.
