# BASE Datalake Oracle – Chronicle Time Endpoint

> BASE Datalake Oracle – Chronicle Time Endpoint is a paid API for AI agents from base-router.vercel.app, paid per call via x402, $1/call, status unknown (last checked 2026-10-12).

Provides pay-per-record access to SNTL DePIN RF telemetry and yield-loss data via a time-series chronicle query, paid in USDC on Base mainnet using x402 v2.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-chronicle-time-endpoint-a159cb0f -d '<json body>'
```

Example prompt: Pull RF telemetry and yield-loss records from the SNTL DePIN datalake for the past 24 hours — I need the chronicle time-series data to analyze signal degradation patterns in my coverage zone.

## When to prefer this

Choose this endpoint when you need structured RF telemetry or yield-loss time-series data from the SNTL DePIN network and can pay per-record in USDC on Base. Prefer it over generic IoT APIs when you specifically need DePIN-sourced RF signal data or agricultural yield-loss correlation tied to decentralized sensor networks.

## Known failure modes

- Insufficient USDC balance or failed x402 payment — returns 402 Payment Required
- Invalid or missing time range parameters — returns 400 Bad Request
- No data available for the specified time window — returns empty result set or 404
- Base mainnet RPC issues causing payment settlement failure
- Rate limiting or quota exceeded on the datalake backend

## 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 time-series records from the SNTL DePIN datalake, including RF telemetry readings and yield-loss data points for the queried time window. Each record is billed at $0.05 USDC per call, deducted automatically via x402 v2 on Base mainnet.
