get_ohlcv

Read-only

Get stored end-of-day OHLCV candles for a stock, ETF, or crypto ticker, daily or weekly. Use this for exact-return calculations, charts, and backtests after get_summary identifies a setup. Results are paginated; pass next_cursor back as cursor to continue. Equity and ETF bars are split-and-dividend adjusted; crypto bars are unadjusted. Credit cost is 1 credit per 100 bars returned, rounded up, with a 1 credit minimum.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
endNoInclusive end date (YYYY-MM-DD). Compared against the candle date.
limitNoMaximum candles to return (1-1000). Default: 100.
orderNoSort by candle date. Default: desc.
startNoInclusive start date (YYYY-MM-DD). Compared against the candle date, so for weekly this is the Sunday week end. Lookback is limited by plan.
cursorNoExclusive date cursor from next_cursor for pagination (YYYY-MM-DD).
tickerYesTicker symbol, e.g. AAPL, BTCUSD, SPY
timeframeNoCandle timeframe. Default: daily. Weekly candles cover Monday-Sunday and are dated by the Sunday week end, matching get_summary with timeframe=weekly. The in-progress week is not returned.

A4.5/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses important behavioral traits beyond the readOnlyHint annotation: pagination via next_cursor, split-and-dividend adjustment for equities/ETFs vs unadjusted crypto, and credit cost details. These are valuable and not present in the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is three sentences, each with distinct value: purpose+use case, pagination, and behavioral caveats. It is front-loaded with the primary function, then adds necessary detail without wordiness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With a rich output schema and comprehensive parameter descriptions, the main description covers all key non-obvious aspects: use case, pagination, adjustment policies, and credit cost. It is adequate for an agent to select and invoke the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% description coverage, so the schema already documents all parameters in detail. The description adds contextual info like pagination and adjustments that relate to parameters but does not repeat or enhance individual parameter semantics beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description begins with a specific verb ('Get') and resource ('stored end-of-day OHLCV candles') and clearly scopes to stock, ETF, or crypto ticker with daily or weekly timeframes. This distinguishes it from sibling tools like get_summary or get_search.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly states when to use the tool: 'for exact-return calculations, charts, and backtests after get_summary identifies a setup.' It gives clear context and references the workflow with get_summary, though it does not explicitly name alternatives or conditions to avoid using it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.7/5.0
Disambiguation5/5

Each tool targets a distinct resource/action: watchlist mutations, account info, raw candles, schema metadata, filtered searches, per-ticker summaries, and watchlist-wide summaries/deltas. The descriptions explicitly call out when to prefer one tool over another, especially get_watchlist vs get_summary vs get_watchlist_changes.

Naming Consistency5/5

Tool names follow a consistent get_* pattern for retrieval operations, with add_to_watchlist and remove_from_watchlist as clear mutating counterparts. snake_case verb_noun naming is uniform across all 9 tools.

Tool Count5/5

Nine tools is well within the ideal range and each tool earns its place. The set covers data discovery, analytics, raw data access, account management, and watchlist lifecycle without redundant or bloated surface area.

Completeness5/5

The domain of market intelligence and watchlist management is well covered: search/screen, per-ticker summaries, OHLCV data, watchlist add/remove/list, change tracking, schema discovery, and account limits. No obvious dead ends or missing core operations for the stated purpose.
