## 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 obol-base-address-snapshot-9494c6c3
```

Example prompt: Pull a verified on-chain snapshot for the Base address 0x1234...abcd — I need to see its current state and activity.

## When to prefer this

Choose this endpoint when you need verified, trustworthy on-chain data for a specific Base network address and are willing to pay a micro-fee ($0.001 USDC) per query. Prefer it over free unverified RPC calls when data integrity and provenance matter, such as compliance checks, portfolio audits, or agent workflows requiring confirmed blockchain state.

## Known failure modes

- Invalid or malformed address string returns an error
- Address not found or never used on Base returns empty or null data
- Payment failure via x402/USDC prevents data delivery
- Network or RPC errors may cause temporary unavailability
- Rate limiting or quota exhaustion may block repeated calls

## How this service works

Obol sells verified blockchain data over x402, settled in USDC on Base.

## Output

A verified snapshot object containing on-chain data for the specified Base network address, potentially including balance information, transaction history, token holdings, and current account state at the time of the query.
