Ethereum Raw Storage Slot Reader (eth_getStorageAt)
x402
Ethereum Raw Storage Slot Reader (eth_getStorageAt) is a paid API for AI agents from skills.onesource.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Reads a raw 32-byte storage slot from any Ethereum-compatible smart contract at a given block using eth_getStorageAt

How this service works
Read a raw storage slot from any Ethereum contract via eth_getStorageAt
Output
Returns the raw 32-byte hex value stored at the specified storage slot of the target contract on the specified network at the specified block. This is the low-level EVM storage output, suitable for decoding into addresses, integers, booleans, or other Solidity types.
Example use cases
Example prompt
“What is the raw 32-byte value stored in slot 0x0 of the contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum at the latest block?”
Technical details
Endpoint
GEThttps://skills.onesource.io/api/chain/storageWhen to prefer
Use this endpoint when you need the lowest-level, raw storage access to any EVM contract — especially for reading non-standard or unverified storage layouts, inspecting proxy slots directly, or auditing contract state at a specific historical block. Prefer this over higher-level contract-read endpoints when the ABI is unavailable, the slot is known, or you need deterministic hex output for further decoding.
Side effects
- Invalid contract address format returns validation error
- Invalid slot hex pattern returns 400 bad request
- Contract does not exist at specified block returns zero bytes (0x000...000)
- Unsupported network name returns 400 or 422
- Block number out of range or not yet mined returns error
- Payment not provided or insufficient (x402) returns 402 Payment Required
