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 13 APIs on the APIs.io network, including Auth API, Quote API, Session API, and 10 more. Tagged areas include AI Agents, Asset Transfer, Bridge, Cross-Chain, and Non-Custodial.

The AssetFare catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

AssetFare’s developer surface includes authentication, pricing, and 25 more developer resources.

scored 2026-10-04 · rubric v0.23.0
Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
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.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
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.
