## 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 base-datalake-oracle-664b989d -d '<json body>'
```

Example prompt: Pull the latest SNTL DePIN RF telemetry and yield-loss records from the BASE Datalake Oracle — I need to analyze signal coverage and crop yield-loss data for my DePIN network nodes.

## When to prefer this

Choose this endpoint when you need raw DePIN RF telemetry or yield-loss data from the SNTL sensor network and are willing to pay per record via USDC on Base mainnet. It is the only known oracle for SNTL DePIN datalake records and is suited for agents that have a Base wallet and need pay-as-you-go access without a subscription.

## Known failure modes

- Insufficient USDC balance on Base mainnet — payment fails and no data is returned
- Invalid or malformed query parameters — returns error with no records
- Rate limiting or quota exceeded — request rejected
- Network or oracle unavailability — timeout or 5xx error
- Records not found for given query criteria — empty result set

## How this service works

Pay-per-record access to the SNTL DePIN RF telemetry &amp; yield-loss datalake. x402 v2, USDC on Base mainnet.

## Output

Returns structured records from the SNTL DePIN datalake containing RF telemetry readings and yield-loss metrics. Each call returns pay-per-record data charged at $0.05 USDC via x402 v2 on Base mainnet.
