## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-base-storage-slot-c0196504 -d '<json body>'
```

Example prompt: Can you read storage slot 0x0 at contract address 0x1234...abcd on Base — I want to see the raw value stored there?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
