Wormhole

Wormhole is a decentralized cross-chain messaging and interoperability protocol connecting 45+ blockchain networks. It provides REST APIs for querying VAA (Verifiable Action Approval) status, native and wrapped token transfers, cross-chain operations, and Guardian Network data via the Wormholescan API. Developers can build multichain applications with the TypeScript SDK, CLI tooling, and the Connect bridging widget.

Wormhole publishes 3 APIs on the APIs.io network: Guardian API, wormhole API, and wormholescan API. Tagged areas include Cross-Chain, Blockchain, Interoperability, DeFi, and Token Transfers.

The Wormhole catalog on APIs.io includes 1 Spectral governance ruleset.

Wormhole’s developer surface includes developer portal, GitHub presence, engineering blog, status page, and 11 more developer resources.

Kin Score

Kin Score Kin Score How this is scored →
scored 2026-09-08 · rubric v0.20.0
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/wormhole: open an issue to ask a question, or submit a pull request to add artifacts.
