Qveris

QVeris

QVeris is a paid capability marketplace for global market, fundamental, macro, derivatives, crypto, China/HK, news, filings, and alternative-data calls. Use it when the built-in free sources cannot cover the requested dataset, when the user explicitly asks for QVeris, or when a premium provider is needed for depth such as options Greeks, analyst/calendar feeds, broad provider comparison, or paid China/HK/global coverage. For ordinary OHLCV, keep source: "auto" on the free loader chain unless the user explicitly selects source: "qveris".

Signup link: QVeris via Vibe-Trading. Invite code fallback: Vyjjo5G_1cAHJA.

Workflow

1. Discover with qveris_search

Call qveris_search first. Search is free and returns candidate capabilities with tool_id, provider, parameters, examples, expected_cost, billing rule, categories, and stats such as success_rate and average execution time.

Good queries are concrete:

• US listed options chain implied volatility Greeks AAPL
• Hong Kong market daily OHLCV financial statements
• FRED CPI Treasury yield curve macro series
• China A share northbound fund flow daily

2. Inspect with qveris_inspect

Call qveris_inspect on one or more tool_id values before any paid call. Inspect is free and returns the fuller parameter schema and sample parameters. Use it to verify required parameters, enum values, date formats, and output shape before execution.

3. Call with qveris_execute

Call qveris_execute only after the user has enabled QVeris and the tool has been inspected. Pass the inspected tool_id, the exact parameters, and a reasonable max_response_size. Use session_id and search_id when available so usage can be reconciled later.

Choosing a Capability

Prefer the candidate with the best combination of:

1. High stats.success_rate.
2. Low expected_cost for equivalent data.
3. Provider fit for the task: official or specialist sources before generic mirrors when the figure matters.
4. Parameter clarity: required fields and examples should match the user's requested asset, date range, and granularity.

Do not assume tools with similar names are interchangeable. The measured catalog has very large quality variance inside the same category; design notes recorded FMP tools ranging from near-zero to 100% success and some tradefeeds tools at 0%. Surface success_rate and expected_cost in the answer whenever the user is choosing among paid options.

Billing and Modes

• The default free route is Vibe-Trading's built-in public data stack; QVeris tools are unavailable in mode="free".
• Discover (qveris_search) and inspect (qveris_inspect) are free only after the user explicitly enables the paid QVeris route.
• Execute (qveris_execute) is paid only when the provider call is billable.
• Failed calls, empty results, and parameter errors are not charged by the QVeris contract; observed missing-parameter calls returned success=false, cost=0.0, status=not_charged, and unchanged balance.
• mode="free" means the original free public-data path stays active and QVeris is hidden from agent/tool/backtest routing.
• mode="paid" permits QVeris discovery, inspect, and execute calls, bounded by budget_credits_per_session. Only a flat per-call quote (24.2 credits, 1 credits/call) can be reserved against that budget. A quote priced per result, row or value is refused as quote_not_bounded, because its leading number is not the bill: 1 credits/result charged 9.66 credits for one stock-year.
• source: "qveris" in a backtest or get_market_data serves crypto, forex, futures and macro bars only. Stocks, ETFs and other markets with splits and dividends are refused: the loader picks a capability by search rank, which ignores price adjustment, so it could not say how the bars were adjusted.
• Never hide cost: every successful execute result should preserve cost and remaining_credits for the user.

Configuration can come from QVERIS_API_KEY / QVERIS_BASE_URL, or from Settings -> QVeris / vibe-trading data mode paid. If QVeris is disabled, in free mode, or no API key is configured, the tools should be treated as unavailable.

Truncation

qveris_execute accepts max_response_size (20480 default, -1 means do not ask QVeris to truncate). When a response is too large, QVeris returns a result object containing a message, truncated_content, and full_content_file_url. If the full JSON is required, fetch that signed URL and use the full payload. If a summary is enough, cite that the response was truncated and work only from truncated_content.

Balance and Usage

Check balance and recent usage through:

• Web: Settings -> QVeris.
• CLI: vibe-trading data status or vibe-trading data usage.
• Agent/API tools: status is derived from free search/ledger/usage endpoints.

For reconciliation, prefer execution_id, tool_id, charge_outcome, cost, and remaining_credits over text summaries.
