A non-custodial routing API for AI agents that returns fee-inclusive cross-chain and same-chain quotes and bounded unsigned actions; the caller's own wallet verifies, signs and submits every transaction, and AssetFare never holds keys, signs or submits. Its live v2 capabilities document (checked 2026-10-03) lists 16 chains, 20 asset endpoints and 54 active directed routes (a further 44 measured routes are inactive), with a USD 1 minimum, no business maximum and an exact 1 bp service fee on top of provider and network fees. The v2 REST contract covers capabilities, quote, prepare, a receipt-driven session lifecycle and status; the same surface is offered over MCP and A2A, and a legacy v1 compatibility API remains live.
AssetFare publishes 6 API contracts indexed on the APIs.io network, including Capabilities API, Prepare API, Quote API, and 3 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, getting-started guide, documentation, and 30 more developer resources.
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.

Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
Reads the live v2 capability document: chains, asset endpoints, active and inactive directed routes, fee policy, amount policy and execution availability.
Quote-bound, idempotent, receipt-driven sessions for multistep routes: create, read, observe source and output receipts, and refresh an expired unsubmitted action.
The earlier v1 route API (wallet auth, quote, session and status), still served for compatibility and listed in the provider's API catalog as a legacy anchor beside v2.
Overlays applied on top of this provider's contracts. Each card says who wrote it: a document the provider publishes, or one API Evangelist derived or generated.
