Get best available line using event_id query

v2GetBestOdds

Read-onlyIdempotent

Get best available line using event_id query Returns the best currently open sportsbook price for one event market, plus the ranked matching prices. This endpoint is event-scoped, so no date parameter is required. Read-only Product data or price calculation. Use returned canonical IDs. Access, delay and metered usage follow your connected account; never infer coverage from an empty result. One bounded request, no background polling or automatic retry. Affiliate 27 is excluded. No wagers, account changes or guarantee of returns.

B3.3/5.0

Behavior4/5

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

Annotations already cover read-only, idempotent, non-destructive. The description goes beyond them with real operational context: access/delay/metered usage follow the connected account, empty results must not be read as lack of coverage, one bounded request with no polling or retry, and affiliate 27 exclusion. That is substantive disclosure beyond the structured fields.

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

Conciseness3/5

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

It is front-loaded with the core purpose, which is good, but the opening echoes the title verbatim and the back half is a dense run-on chain of constraints. The affiliate-27 exclusion is duplicated between description and schema. Several sentences earn their place; a few are padding or repetition.

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

Completeness3/5

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

An output schema exists, so return values need not be explained, and annotations cover the safety profile. The description adequately covers scope and usage constraints, but for a tool sitting among dozens of near-identical best-line/best-odds siblings, the absence of any disambiguation leaves a real gap in completeness.

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

Parameters2/5

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

Reported schema description coverage is 0% at the top level, so the description is expected to compensate, yet it adds almost nothing about the nested query fields. It only notes that no date parameter is needed and repeats the affiliate-27 exclusion already present in the affiliate_ids schema description. Line, side, limit, period, and participant semantics are left entirely to the schema.

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

Purpose4/5

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

The first two sentences state a specific verb and resource: returns the best currently open sportsbook price for one event market plus ranked matching prices. That is clearly more than a restatement of the name. However, it never distinguishes itself from close siblings such as v2GetBestOddsByEvent or v2GetBestLineByEvent, which an agent must choose between.

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

Usage Guidelines3/5

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

The description gives one useful routing hint ('event-scoped, so no date parameter is required'), which implicitly contrasts with date-scoped siblings like v2GetBestOddsBySportAndDate. But it never states when to prefer this tool over v2GetBestOddsByEvent or v2GetBestLineByEvent, leaving the sibling choice to inference.

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