AssetFare

A capped, non-custodial routing API for a single corridor — Solana SOL to Base native ETH — aimed at AI agents. It returns fee-inclusive quotes and bounded unsigned actions; the caller's agent verifies, signs, and submits every transaction. AssetFare never receives private keys and never signs or submits, framing itself as one route candidate rather than a market-wide best-price aggregator.

AssetFare publishes 1 API on the APIs.io network: Agent-native Route API. Tagged areas include AI Agents, Asset Transfer, Bridge, Cross-Chain, and Non-Custodial.

AssetFare’s developer surface includes authentication, pricing, and 12 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/assetfare: open an issue to ask a question, or submit a pull request to add artifacts.
