xRoot token operationsA

dev.xroot.api

Read-only tools for agents: everything a Solana or Robinhood Chain wallet can get back (rent, wrapped SOL, LP fees, dead positions, failed deploys), whether a token is safe, when it unlocks, which protocol upgrades are live, and what a token operation costs.

Tessera Analytics - Hyperliquid Market IntelligenceA

dev.tesseralytics

Tessera turns the whole Hyperliquid perp universe into a single cross-section you can query. The hosted MCP server answers the questions a raw-data pipe can't: which markets are crowded, who is paying the most funding, how far one market's funding has diverged from ETH, what open interest and positioning look like across every market on the last completed day, and what the live market is doing right now. Nine tools — four ranking/screening tools, a series tool for one market, a coverage tool, the catalog/dictionary trio, and a live market read — over a completed-day rollup built from the venue's own trade feed. Rows and full history stay on the REST API: three Parquet datasets (order-flow-enriched 1-minute OHLCV, hourly funding, hourly positioning) partitioned per coin-month, downloadable with a key. Free keys work end to end; Pro removes the history and coverage limits.
