assetfare_v2_quote

Read-only

Get a fresh cross-chain quote with amount-specific guidance, route summary, and unsigned prepare requirements; validate hashes, bounds, and TTL without creating approvals or submitting transactions.

Instructions

Get one fresh AssetFare quote with amount-specific economic_guidance, direct_route_summary, continuation_v3, and unsigned_prepare_requirements. Example: quote Solana USDC to Base USDC. price_recommended_for_amount is advisory; compare alternatives when price matters, but no economic acknowledgement field is required. The quote remains an unranked_candidate until separate explicit approval selects one mode. The adapter validates hashes, path, bounds, and TTL and never creates approval, prepares, signs, or submits.

Input Schema

Name	Required	Description
`to_chain`	Yes	Destination chain for the v2 route: Solana, Base, Arbitrum, or Robinhood Chain. Source-only chains are not destinations.
`to_token`	Yes	Output token symbol on to_chain. The chain-token pair must appear in current v2 capabilities.
`amount_usd`	Yes	Requested input value in USD, minimum 1. USD 1 is reachability/schema smoke only. A USD 50 competitive bucket was observed only for dated 2026-09-23 Solana USDC to Base USDC evidence and must not be generalized to another corridor. USD 1,000 is the primary representative amount. SOL input includes a swap. Always quote the actual intended amount.
`from_chain`	Yes	Source chain for the v2 route. Polygon, Optimism, Ethereum, HyperEVM, X Layer, Sei, Sonic, Monad, Avalanche, Cronos, Injective, Linea, Aptos, Unichain, and Ink are source-only and cannot be used as to_chain.
`from_token`	Yes	Input token symbol on from_chain. The chain-token pair must appear in current v2 capabilities.

A3.7/5.0

Behavior4/5

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

Goes well beyond the readOnly/openWorld annotations by disclosing the lifecycle constraint (quote remains an unranked_candidate until a separate explicit approval selects a mode), that no economic acknowledgement field is required, and that the adapter validates hashes, path, bounds, and TTL while never creating approval, preparing, signing, or submitting. This is meaningful context an agent cannot infer from annotations alone.

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

Conciseness4/5

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

Front-loaded with the core action and return contents, followed by an example and then the guardrails. Dense terminology (unranked_candidate, continuation_v3, unsigned_prepare_requirements) is used without definition, but every sentence carries a distinct constraint rather than restating the tool name.

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

Completeness4/5

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

An output schema exists, so the description does not need to explain return shapes, and it is complete on the operational side: validation scope, non-mutating guarantees, and the approval-gating rule are all stated. The only shortfall is that it does not explicitly route the agent to the sibling needed after quoting (prepare or selected-candidate).

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 coverage is 100% and the schema itself carries the substantive detail (amount_usd guidance on USD 1 vs 1,000, source-only chain exclusion on from_chain). The description adds only the 'amount-specific' framing and a single example corridor, so it neither repeats nor meaningfully extends the parameter documentation.

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?

Specific verb+resource ('Get one fresh AssetFare quote') with an enumeration of what the response carries (economic_guidance, direct_route_summary, continuation_v3, unsigned_prepare_requirements). It also distinguishes itself from the selection path by noting the quote stays an unranked_candidate, though it never names assetfare_v2_quote_selected_candidate or assetfare_v2_route_selection explicitly.

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?

Provides an example corridor and a caveat that price_recommended_for_amount is advisory and alternatives should be compared when price matters, which implies usage but does not say when to call this versus the selected-candidate or route-selection siblings. The 'compare alternatives' instruction is given without naming the tool that does the comparison.

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