Hydromancer

Hydromancer is data infrastructure for the Hyperliquid ecosystem, offering real-time REST and WebSocket APIs, L2/L4 orderbook streaming, liquidations feeds, oracle and perp/spot price data, HIP-3/HIP-4 market events, and granular historical datasets (via its Reservoir exports). The REST API is a single POST /info dispatcher with Bearer-token authentication and token-metered subscription pricing; the WebSocket API delivers low-latency streams with tiered connection and subscription limits. Documentation is agent-native (llms.txt plus Markdown twins of every page). Onboarding is manual, with a discretionary free tier for public-goods and early-stage teams.

Hydromancer is listed with 2 APIs on the APIs.io network. Tagged areas include Hyperliquid, Blockchain, Web3, DeFi, and Crypto trading data.

Hydromancer’s developer surface includes changelog, sandbox, authentication, documentation, API reference, pricing, engineering blog, and 13 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document

9 more unmet checks in the Agent Readiness table above.

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.
