Get Jupiter quote

get_quote

Fetches a Jupiter swap quote for a token pair and amount, returning expected amounts, route, slippage, and referral fees without building a transaction.

Instructions

Free Jupiter Swap API V2 quote (GET /swap/v2/order, no taker). Returns amounts, route, slippage, and referral fee fields. Does not return a transaction.

A3.8/5.0

Behavior4/5

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

With no annotations, the description carries the disclosure burden and does well: it identifies the endpoint, says it is free, specifies 'no taker', describes the returned fields, and explicitly states that no transaction is returned. It omits error behavior, rate limits, and auth details, but covers the key behavioral traits for a read-only quote call.

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 compact sentences with the endpoint and key distinction front-loaded. Every sentence adds useful information, including the explicit non-return of a transaction.

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?

There is no output schema, and the description usefully summarizes the returned fields and explicitly says no transaction is returned. However, it leaves the four input parameters undocumented and does not address error cases or execution boundaries, so an agent can call it but must rely on the schema alone to understand the inputs.

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?

Schema description coverage is 0% and there are four parameters, yet the description does not explain inputMint, outputMint, amount, or slippageBps. It mentions that quotes include slippage, but not what the caller must supply or what units/constraints apply, so it fails to compensate for the schema's lack of parameter descriptions.

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 states a specific verb and resource: a free Jupiter Swap API V2 quote via GET /swap/v2/order with no taker. It also clarifies what the tool returns (amounts, route, slippage, referral fee fields) and what it does not return (a transaction), which distinguishes it from build_swap_tx.

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 note that it does not return a transaction implies this is a preview/quote step and that build_swap_tx is the execution step, but no sibling is named and there is no explicit when-to-use or when-not-to-use guidance. Usage is inferable but not stated.

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