# SNTL DePIN Oracle – Critical Wallets RF Telemetry Endpoint

> SNTL DePIN Oracle – Critical Wallets RF Telemetry Endpoint is a paid API for AI agents from sntl-router.vercel.app, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-13).

Fetches pay-per-record RF telemetry and yield loss data for critical wallet addresses from the SNTL DePIN datalake, settling payment in USDC on Solana.

## 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 sntl-depin-oracle-critical-wallets-rf-telemetry-endpoint-facefeef
```

Example prompt: Pull the latest RF telemetry and yield loss records for my critical DePIN wallet from the SNTL oracle — I need the most recent sensor readings and I'm happy to pay the $0.50 USDC per-record fee.

## When to prefer this

Choose this endpoint when you need RF telemetry or yield loss data specifically from the SNTL DePIN oracle network for critical wallet addresses and are set up to pay per-record in USDC via the x402 protocol on Solana. Prefer this over general IoT or telemetry APIs when the data must come from SNTL's decentralized sensor network, and over other SNTL endpoints when the scope is specifically critical wallet tiers.

## Known failure modes

- Insufficient USDC balance — payment settlement fails and data is not returned
- Invalid or missing wallet property parameters — returns empty or error response
- x402 payment protocol misconfiguration — 402 Payment Required error with no data
- Vercel cold-start latency or timeout — request times out before data is returned
- No records found for queried wallet properties — empty dataset returned
- Solana network congestion causing payment settlement delays

## How this service works

Pay-per-record access to the SNTL DePIN RF Telemetry & Yield Loss Oracle datalake. Settles in USDC on Solana to the SNTL treasury.

## Output

Returns one or more records from the SNTL DePIN RF telemetry and yield loss oracle datalake corresponding to critical wallet addresses. Each record contains RF sensor readings, yield metrics, and associated DePIN node data. Payment of $0.50 USDC per call is settled to the SNTL treasury on Solana via the x402 protocol before data is released.
