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. Requests default to https://qveris.ai/api/v1; an audited test run may set QVERIS_BASE_URL=https://api.qveris.cloud/api/v1. The client rejects non-HTTPS and non-QVeris hosts.

Finance CAP requirement: For qveris_finance.* workflows, use the standardized CAP endpoints (/capabilities, /capabilities/{id}, /capabilities/query). When this repository is available, use scripts/qveris_tool.mjs cap-detail/cap-query as the public adapter: it resolves current CAP IDs from the live catalog, validates against live cap-detail, normalizes inputs, retries one transient control-plane fetch failed, performs at most one budget-permitted parameter or explicitly-retryable data retry (--max-attempts 1|2), and records exact observed Trace. Legacy /search plus /tools/execute, generic discover/call, and raw finance tool IDs are not fallbacks. If the standardized CAP runtime is unavailable, report tool_runtime_missing or capability_unavailable instead of selecting a raw provider route.
