Idle Finance

Idle Finance is a decentralized yield automation protocol that has operated since 2019, enabling users and integrators to optimize yield generation across DeFi. The platform offers REST APIs for querying Best Yield and Yield Tranches pools, APY and TVL metrics, historical rates, and governance staking information. Idle aggregates yield sources across protocols such as Compound, Aave, Morpho, and Clearpool, and supports multiple chains including Ethereum, Polygon, Polygon zkEVM, and Optimism.

Idle Finance publishes 3 APIs on the APIs.io network: Pools API, Rates API, and TVL API. Tagged areas include DeFi, Yield Optimization, Finance, Crypto, and Staking.

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

Idle Finance’s developer surface includes authentication, documentation, status page, engineering blog, and 12 more developer resources.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

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/idle: open an issue to ask a question, or submit a pull request to add artifacts.
