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 8 API contracts indexed on the APIs.io network, including Health API, Legacy API, Metadata API, and 5 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 7 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 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.

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/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
