Utila

Utila is an institutional digital asset wallet and stablecoin infrastructure platform for fintechs and enterprises. Built on MPC (multi-party computation) key management, it provides secure custody with policy-driven governance, embedded compliance and AML screening, and a resource-oriented REST API for programmatically managing vaults, MPC wallets, addresses, balances, and transactions across many blockchains — including sponsored (gas-abstracted) transfers, transaction simulation, an automated Co-Signer for signing workflows, webhooks, and a first-party CLI.

Utila publishes 7 APIs on the APIs.io network, including Address Book API, Assets API, Balances API, and 4 more. Tagged areas include Company, Web3, Digital Assets, Stablecoins, and Custody.

The Utila catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Utila’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, support, authentication, and 28 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments 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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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/utila: open an issue to ask a question, or submit a pull request to add artifacts.
