# Carbon & Cashmere Oracle Divergence API – SOL

> Carbon & Cashmere Oracle Divergence API – SOL is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.03/call, status down (last checked 2026-09-14).

Returns real-time oracle price divergence statistics between Pyth and CoinGecko for Solana (SOL), including spread percentages, exceedance rates, and timestamped divergence events.

## Facts

- Endpoint: GET https://api.carbon-cashmere.de/v1/oracle-divergence/SOL

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 carbon-cashmere-oracle-divergence-api-sol-dce39b2f
```

Example prompt: Pull the latest Pyth vs CoinGecko oracle divergence stats for SOL — I want to see the spread percentages, how often it's exceeded the threshold, and any recent divergence events from the past hour.

## When to prefer this

Use this endpoint when you need to detect, measure, or monitor discrepancies between Pyth on-chain oracle prices and CoinGecko reference prices for SOL specifically — ideal for DeFi risk monitoring, oracle manipulation detection, arbitrage signal generation, or validating price feed health before executing trades.

## Known failure modes

- Unsupported coin symbol returns 404 or empty response
- Pyth feed temporarily unavailable causes partial or error response
- CoinGecko rate limiting causes stale or missing reference price
- No divergence events in window returns empty events array with valid stats
- Payment not received (x402) results in 402 Payment Required response

## How this service works

Professional crypto market intelligence. Real-time prices, signals, and market scoring.

## Output

A JSON object containing: the coin identifier (SOL), spread statistics (p25, p75, median, abs_max, abs_p95 in percent), exceedance rate and count, a list of timestamped divergence events with direction (pyth_lower/pyth_higher), individual Pyth and CoinGecko prices, Pyth confidence values, and the most recent price snapshot with spread — all filtered by configurable lookback window and threshold.
