Match market prices

get_match_odds
Read-onlyIdempotent

Match-winner market prices for a match: implied probability per player, with bid, ask and mid. Requires the PRO plan. Match rows carry has_market, so check it first. A match with no market mapped has no prices to return.

Input Schema

NameRequiredDescriptionDefault
limitNoMaximum price points to return (1-200).
match_idYesMatch id, as returned by get_live_matches, get_upcoming_matches or get_recent_results.

Output Schema

NameRequiredDescriptionDefault
okYesTrue when the request succeeded, including when the answer is an empty list. False for a missing or rejected key, a plan that does not include this data, an unknown id, a rate limit or a network error. The message then says what to do. check_api_status is the exception: it is true whenever the API answered, and reports API key problems in the message.
marketNoThe match-winner market.
messageYesHuman-readable summary of the result, safe to relay to the user verbatim.

A4.3/5.0
Behavior4/5

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

Annotations already declare readOnly/idempotent safety, so the description correctly spends its words on what annotations can't say: the PRO plan requirement and the empty-result behavior for unmapped markets. It does not mention rate limits or result ordering, which keeps it short of a 5.

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?

Four short sentences, front-loaded with what is returned, then the plan requirement, then the precondition. Each sentence carries a distinct, actionable fact.

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?

For a read-only, two-parameter tool with a full output schema and complete schema coverage, the remaining unknowns are access requirements and empty-result cases, and both are covered here.

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?

Schema description coverage is 100% – both match_id and limit are already documented, including where match_id comes from. The description adds no parameter-level detail beyond the schema, so the baseline 3 applies.

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?

States a specific verb and resource: match-winner market prices for a given match, and names the exact payload (implied probability per player plus bid, ask, mid). No sibling tool covers markets, so an agent can route here without opening the schema.

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?

Gives an explicit precondition ('Match rows carry has_market, so check it first') and a clear failure condition ('A match with no market mapped has no prices to return'), plus the PRO plan gate. It doesn't point at alternatives, but none of the siblings overlap with market pricing.

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