AssetFare USDC Bridge

assetfare_v2_quote

Read-only

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

TableJSON 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?

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=true and idempotentHint=false, yet the description adds genuine behavioral context beyond them: 'The adapter validates hashes, path, bounds, and TTL and never creates approval, prepares, signs, or submits', plus the advisory nature of price_recommended_for_amount and the candidate-not-commitment status of the quote. Lacks any note on quote freshness/TTL or rate limits, which would have earned 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.

Conciseness4/5

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

Five sentences, front-loaded with the purpose and output list, with no filler. Dense internal vocabulary (unranked_candidate, continuation_v3, unsigned_prepare_requirements) makes it jargon-heavy for an outside reader, but each sentence still carries a distinct constraint.

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?

The tool is a read-only quote with an output schema present, so return values need not be explained — and the description wisely stops at naming the response fields rather than restating their shape. It supplies the workflow position (candidate → approval → prepare) and the no-side-effect guarantee, which is sufficient for correct invocation; only the explicit sibling routing is missing.

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%, so the schema already carries the load — enums, amount minimums, the USD 50 evidence bucket caveat, and the source-only chain list are all documented there. The description only adds a single example corridor ('quote Solana USDC to Base USDC'), which is the correct baseline-3 outcome when structured fields already do the work.

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?

States a specific verb and resource ('Get one fresh AssetFare quote') and enumerates the amount-specific outputs the caller receives (economic_guidance, direct_route_summary, continuation_v3, unsigned_prepare_requirements). It gestures at the selection workflow ('remains an unranked_candidate until separate explicit approval selects one mode') but never names the sibling it is distinct from (assetfare_v2_quote_selected_candidate, assetfare_v2_route_selection), so differentiation is inferable rather than stated.

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?

Usage is implied rather than stated: 'compare alternatives when price matters' and 'no economic acknowledgement field is required' hint at a quote-then-select flow, and 'until separate explicit approval selects one mode' points downstream. However, it never says when to prefer this tool over assetfare_v2_route_selection or the selected-candidate variant, nor what prerequisites exist, leaving the agent to infer the workflow.

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