How this service works
Read one storage slot on Base for $0.001 USDC via eth_getStorageAt. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
A hex-encoded 32-byte value representing the raw contents of the requested storage slot at the specified contract address and block on Base, returned as a JSON response mirroring the eth_getStorageAt RPC result.
Example use cases
Inspect ERC-20 total supply slot
“Read storage slot 0x2 on Base for the USDC contract at 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA so I can see the raw packed total supply value.”
Debug a mapping storage key
“Can you fetch storage slot 0xabc123... for the contract at 0x4200000000000000000000000000000000000010 on Base? I computed the keccak slot for a specific mapping key and need to verify what's stored there.”
Monitor an upgradeable proxy implementation slot
“Check the EIP-1967 implementation slot 0x360894a13ba1a3210667c828492db98dca3e2076cc3735a920a3ca505d382bbc on the proxy contract 0xSomeProxy on Base — I want to confirm which implementation address is currently set.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/base-storageWhen to prefer
Choose this endpoint when you need a cheap, pay-per-call way to read raw EVM storage on Base without running your own node or managing RPC subscriptions. It is ideal for agents that occasionally need to inspect smart contract state, verify on-chain values, or debug storage layouts without the overhead of a full Web3 infrastructure setup. Prefer it over general-purpose RPC providers when you want metered micropayment billing via x402 with no API key management.
Side effects
- Invalid contract address format returns an error
- Out-of-range or malformed slot index causes a bad request response
- Specified block number not yet finalized or too far in the past may return null or error
- Payment failure (insufficient USDC balance or x402 flow error) blocks the request
- Network congestion on Base RPC may cause timeout or slow response
