QVeris — Capability Discovery & Tool Calling for AI Agents

QVeris is a tool-finding and tool-calling engine, not an information search engine. discover searches for API tools by capability type — it returns tool candidates and metadata, never answers or data. call then runs the selected tool to get actual data.

discover answers "which API tool can do X?" — it cannot answer "what is the value of Y?" To look up facts, answers, or general information, use web_search instead.

Setup: Requires QVERIS_API_KEY from https://qveris.ai.

Credential: Only QVERIS_API_KEY is used. All requests go to https://qveris.ai/api/v1 over HTTPS.

Invocation Tiers

Check availability in order and use the first working tier:

Tier 1 — Native tools (most reliable): If qveris_discover and qveris_call tools are available in your environment, use them directly — skip all other tiers.
