Mint Intel: Ethereum chain data

ETH/USD read straight from Ethereum state, no CEX or API key: the Chainlink ETH/USD feed (latestRoundData) plus the Uniswap v3 WETH/USDC 0.05% pool spot price in one RPC batch. Median of fresh sources, per-source price, feed age and round, spread in bps.

Simulate a Solana transaction before sending it via simulateTransaction (sigVerify off, recent blockhash replaced, nothing is sent): success or the exact error, compute units consumed, fee in lamports, program logs, return data. Pass ?tx= as base58 or base64 (unsigned is fine). Malformed tx -> 400, not charged.

The next Solana slot leaders from getSlotLeaders, merged into 4-slot leader windows: validator identity, vote account, active stake, commission, first/last slot and seconds until each window starts. Route time-critical transactions to the upcoming leaders. ?limit=1..25.

Solana block production for the current epoch via getBlockProduction (cached <=60 s): cluster leader slots, blocks produced, skipped slots and skip rate %, the 10 worst skip rates among validators with >= 40 leader slots, and with ?id= one validator's leader slots, blocks and skip rate (identity or vote account).

Decoded Solana address lookup table used by v0 transactions: authority (or frozen), active vs deactivated, deactivation and last-extended slots, address count and every stored address (<= 256), via getAccountInfo jsonParsed. Not a lookup table -> 404, not charged.

Decoded Solana durable nonce account: the stored nonce (use it as recentBlockhash for offline or delayed signing), nonce authority, fee per signature and balance, via getAccountInfo jsonParsed. Not a nonce account -> 404, not charged.

Latest Base block height - current chain tip via eth_blockNumber (cached <=1 s). The cheapest liveness / clock tick for Base agents.

Base network info - chain ID, block height, chain head age, gas price, base fee, priority fee, block gas used/limit and RPC client version in one batched RPC call (eth_chainId + eth_getBlockByNumber + eth_gasPrice + eth_maxPriorityFeePerGas).

Base gas oracle - current and next-block base fee, priority-fee percentiles (p10/p50/p90 over the last 20 blocks via eth_feeHistory), slow/standard/fast maxFeePerGas suggestions, legacy eth_gasPrice, the L1 base fee and the cost of an ETH transfer, ERC-20 transfer and DEX swap in ETH and USD.

ETH/USD read straight from Base state, no CEX or API key: the Chainlink ETH/USD feed (latestRoundData) plus the Uniswap v3 WETH/USDC 0.05% pool spot price in one RPC batch. Median of fresh sources, per-source price, feed age and round, spread in bps.

Confirmation status of a Solana transaction signature: found, slot, processed/confirmed/finalized, success or error (searches history). Poll this after sending a tx.

Current Solana mainnet slot, block height and epoch (confirmed commitment, cached <=0.4 s). The cheapest liveness/clock tick for agents.

Latest Solana blockhash + lastValidBlockHeight for building and signing transactions (confirmed, cached <=1 s).

Solana epoch number, slot index, slots remaining, progress % and ETA seconds to the next epoch (staking/reward timing).

Recent Solana prioritization fees (micro-lamports/CU) over the last ~150 slots: p25/p50/p75/p90/max, non-zero percentiles and low/medium/high/veryHigh suggestions. Optional ?accounts= to scope to hot accounts.

Derives the associated token account for owner + mint (SPL and Token-2022 candidates), reports which program the mint uses, whether the ATA exists and its balance. Saves a create-ATA round trip.

Latest transaction signatures touching a Solana address (newest first): slot, time, success/err, memo, confirmation status. ?limit=1..25.

The newest pump.fun coin launches seconds after creation: mint, creator, create signature, slot, time, age in seconds, Create vs CreateV2 (Token-2022). Chain into /v1/sol/mint, /bonding and /holders.

Top token holders of a Solana mint (up to 20 largest accounts) with owners resolved, % of supply, wallet vs program-owned, labels for pump.fun curve / PumpSwap / Raydium / Meteora / Orca pools and burn, plus top-1/5/10/20 concentration and top-10 excluding pools/curves. Optional ?n=1..20.
