Ethereum blob-gas usage and blob-fee evidence when exposed by the configured execution-layer RPC, with explicit unavailable state on pre- or non-supporting providers. Purpose: Measure current blob-space demand without hardcoding protocol capacity assumptions that can change across Ethereum upgrades. 5-minute freshness target; missing evidence is reported explicitly rather than invented.
Annualised realised-volatility estimates over retained 1-hour, 24-hour and 7-day Bitcoin observation windows with minimum-history and coverage gates. Purpose: Compare short and longer Bitcoin realised-volatility horizons using retained point-in-time observations without substituting options implied volatility. 5-minute freshness target; missing evidence is reported explicitly rather than invented.
Cross-venue perpetual-futures funding-rate arbitrage scan across BTC, ETH, SOL and XRP, annualising each venue's rate on its own confirmed interval and ranking spreads into a market-neutral long/short pairing per asset. Purpose: Rank funding-rate arbitrage opportunities across tracked assets and venues as a comparability signal, never a guaranteed-profit claim. 5-minute freshness target; missing evidence is reported explicitly rather than invented.

Use when an agent is building an EIP-1559 transaction and must choose fee caps that will actually get it mined: the base fee plus suggested maxFeePerGas and maxPriorityFeePerGas at slow, normal and fast, computed from the last 20 blocks of real fee history. Do not use for a legacy gas price (/v1/evm/gas) or to price one specific call (/v1/evm/estimate-gas). No API key, no account.
