## 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-signal-api-sol-research-report-157d75f6
```

Example prompt: Pull the Carbon & Cashmere professional research report for SOL — I want the executive summary, current technical state, volatility regime, and the 30-day price data snapshot.

## When to prefer this

Use this endpoint when you need a comprehensive, narrative-style professional research report for Solana specifically, including qualitative sections like executive summary and structural notes alongside quantitative price data. Prefer this over raw price feeds when the user wants interpreted market intelligence rather than just a number. Choose this over the full bundle endpoint when only SOL analysis is needed and cost efficiency matters.

## Known failure modes

- Symbol not supported — endpoint is hardcoded to SOL; other tickers would require a different URL path
- Payment not received or invalid x402 payment header — returns 402 Payment Required
- Upstream market data unavailable — partial or empty sections in the report
- Rate limiting — too many calls in a short window may be throttled
- Stale data — snapshot may lag real-time prices by seconds to minutes
