Built by Metorial, the integration platform for agentic AI.
Decodes an Ethereum L2 batch transaction into human-readable format. Accepts an L1 transaction hash of a batch (pending or confirmed) and returns decoded calldata and blobdata. Supports Optimism, Base, zkSync, Arbitrum, Mode, Zora, Kroma, and Blast batches.
Estimates the gas price needed for a transaction to be included in the next block across 40+ supported chains. Returns confidence-based predictions for both pre-EIP-1559 (Type 0) and EIP-1559 (Type 2) transactions. Supports custom confidence levels and chain selection via chain ID or system/network identifiers.
Retrieves archived Ethereum blob data by versioned hash. Returns the commitment, proof, byte counts, and optionally the full blob data. Stores all blobs that entered the Ethereum mempool (confirmed or not), providing access to historical blob data beyond Ethereum's ~18-day ephemeral storage window.
Lists all on-chain gas estimation oracle contracts supported by Blocknative. Returns metadata including oracle contract addresses by version, RPC URLs, and block explorer links for each supported chain. Useful for interacting with on-chain gas oracles directly.
Retrieves the current distribution and breakdown of gas prices in the Ethereum mempool. Shows the gas prices of the top N transactions eligible for inclusion in the next block. Useful for understanding current mempool pressure and transaction pricing dynamics.
Predicts the Ethereum base fee and blob base fee for the next 5 blocks at 99% and 70% confidence levels. Uses a quantile regression neural network model for predictions. Useful for setting optimal gas fees on Ethereum transactions.
Lists all blockchain networks supported by Blocknative with their metadata including chain ID, architecture, available features, and system/network identifiers. Use this to discover which chains are available for gas estimation and other Blocknative services.
