Blockchain Fee Markets: Predicting Gas Prices for Cost-Optimized Transactions

Solana wallet holdings for any address: native SOL with its USD value at AgentFeed's own on-chain SOL price, every SPL token with mint, symbol and amount (no token prices), and an NFT count. Use when you need to answer: What does this Solana wallet hold? Balances and on-chain metadata via Helius DAS getAssetsByOwner, up to 100 assets.

Liquidation pressure feed: 5-second buckets per symbol of long and short USD liquidated across venues, the dominant side and pressure against the symbol's own baseline, from a gap-free cursor. Use when you need to answer: Which side is being liquidated across venues right now, and how hard compared with normal? One call per 5 s, 10 s on a pass. Heavy pollers: $1 day pass, /api/keys/buy-day-pass.

SPL token metadata for any Solana mint: name, symbol, URI, decimals, total supply, mint and freeze authority, token program, and whether the metadata is still mutable. Use when you need to answer: What is this SPL token? Read from the mint account and its metadata account.

Liquidation stats, 1h and 24h totals for SOL, BTC, ETH, XRP and DOGE: long vs short USD split, biggest single print, and a per-exchange breakdown across Bybit, OKX and Binance. Use when you need to answer: How much was liquidated in the last 1h and 24h?

Solana token pre-trade check: mint and freeze authority, Token-2022 traps, top holders, deepest pool and USD depth, the price impact of $100 and $1,000 buys, pump.fun progress, and a verdict with every rule. Use when you need to answer: What on-chain risks and how much liquidity does this Solana token have before I buy?

Top holders of any SPL token: per-account share with top-1, top-5 and top-10 concentration for a Solana mint. Use when you need to answer: Who holds this SPL token? A deeper cut than the summary in /api/token-risk.

Solana token trade flow: the unique traders over its latest swaps, top-5 share of volume, round-trip wallets, share of brand-new buyer wallets and launch-slot bundle size for mints under 7 days. Use when you need to answer: Who is actually trading this Solana token: many wallets or a few?

Solana token rug check / risk signals for any SPL mint: mint and freeze authority status (revoked is safer), top-1 and top-10 holder concentration, supply, and a list of risk flags. Use when you need to answer: Is this SPL token a rug? Not a honeypot or LP-lock checker.

Everything on the signal board for the coin (price changes, funding, open interest, liquidations with their z-score, whale net position and tilt, flags) plus the 15-minute liquidation cascade probability from our forecast model, the…

BTC price / Bitcoin spot price in USD, live, read on-chain: the median of three Uniswap V3 reads on Base and Ethereum (cbBTC/USDC, and cbBTC and WBTC through WETH/USDC), computed from chain state. Use when you need to answer: What is BTC worth? Returns the price, the read time and the pools that answered.

Solana wallet activity: recent transactions for any address, each with the wallet's SOL and token balance changes, the fee, failures and the programs invoked. Use when you need to answer: What has this Solana wallet been doing? Read from the chain and summarised by us.

Solana holder clusters: the account that first funded each of the top 20 wallets, the clusters sharing a funder and their supply share. Use when you need to answer: Do the top holders of this Solana token share a funder? A shared funder can be an exchange.

SOL price / Solana spot price in USD, live, read on-chain: the median of the two deepest SOL/USDC pools on Solana (Orca Whirlpool, Raydium CLMM), computed from chain state. Use when you need to answer: What is SOL worth? Returns the price, the read time and the pools that answered.

Spot price: the on-chain DEX price for SOL, BTC or ETH, the median of deep USDC pools on Solana, Ethereum and Base read from chain state, and the pools that served it.
