OlympusDAO

OlympusDAO is a decentralized reserve currency protocol built on Ethereum that pioneered protocol-owned liquidity (POL). The Olympus protocol issues OHM, a crypto-native reserve currency backed by a diversified treasury of on-chain assets across Ethereum, Arbitrum, Base, Polygon, Fantom, and Berachain. OlympusDAO provides public REST APIs for querying daily OHM supply, treasury asset holdings, protocol metrics (price, APY, index), and bond market data — powering the Olympus Treasury Dashboard and third-party integrations such as CoinGecko.

OlympusDAO publishes 6 APIs on the APIs.io network, including Health API, Legacy API, Metadata API, and 3 more. Tagged areas include DeFi, Protocol-Owned Liquidity, Reserve Currency, Treasury, and Staking.

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

OlympusDAO’s developer surface includes engineering blog and 3 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/olympusdao: open an issue to ask a question, or submit a pull request to add artifacts.
