Paid services on Base matching “onchain-data”

Crypto perpetual-futures snapshot for a symbol in ONE call (Binance USD-M, keyless): current funding rate and the next funding time, mark and index price, open interest (contracts and USD), 24h price change/high/low/volume, and the top-trader long/short account ratio. For funding arbitrage, leverage/positioning reads, and a derivatives view an onchain-only feed cannot give. Cached 30s.

Solana token mint intel: mint/freeze authority (renounced or live), supply, decimals, SPL vs Token-2022, Token-2022 extensions (permanent delegate, transfer hook, transfer fee, default-frozen, pausable), metadata (name/symbol/uri, mutability) and structural risk flags. Public on-chain facts, no verdict.
