As answered by people managing Hydromancer and DeBounce.
Hydromancer's answer
Hydromancer is a Hyperliquid-only data layer, not an RPC provider. It extends the native API with builder endpoints and batch reads for 1,000+ wallets, and streams the L4 orderbook with maker addresses. The feed is peered to a Foundation node and Hydromancer's own active-set validator, so teams do not have to run that infrastructure themselves.
Hydromancer's answer
The public Hyperliquid API is free, but it rate-limits heavy reads and does not offer these batch or builder endpoints. RPC providers solve node access, not this data layer. Hydromancer is for teams that already have trading access and need faster reads, order-book streaming, and historical data without running their own nodes.
Hydromancer's answer
Hyperliquid builders. That includes trading apps, portfolio and analytics products, HIP-3 and HIP-4 market deployers, and market makers who need low-latency order-book data.
Hydromancer's answer
The team built Hyperdash, a Hyperliquid app later acquired by pvp.trade, and kept hitting the limits of the public API. Hydromancer is the data infrastructure they wanted as builders. It has been Hyperliquid-only since 2024, shaped by teams using it in production. Reservoir, the free historical dataset, is the public-good side of that work.
Hydromancer's answer
A JSON REST API on the same POST /info shape as Hyperliquid, plus WebSocket streaming and a Python SDK. Under that, Hydromancer runs its own Hyperliquid nodes and an active-set validator, peered in AWS Tokyo. Historical data is stored as Parquet on S3. The site does not publish the application languages, so I would not name those here.
Hydromancer's answer
These are teams named on the site and in the docs, not a ranking by revenue.

Have you run your list through a list cleaner/deliverability solution? I use debounce's API (debounce.io) for our product and it is pretty good. Source: over 5 years ago
I use a list taken from GitHub but we also use an API to check if it’s a disposable inbox (https://debounce.io/). Source: over 5 years ago
