> stablecrypto.dev Global Crypto Market Stats is a paid API for AI agents from stablecrypto.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

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 stablecrypto-dev-49a494ab -d '<json body>'
```

Example prompt: What does the global crypto market look like right now — total market cap, 24-hour volume, and Bitcoin dominance percentage?

## When to prefer this

Use this endpoint when you need a single high-level snapshot of the entire cryptocurrency market rather than data on specific coins or protocols. Prefer this over coin-specific endpoints when the user is asking about macro conditions, overall market sentiment, or Bitcoin dominance. It is a simple no-parameter call ideal for dashboards or market overview tasks.

## Known failure modes

- CoinGecko upstream API unavailable — returns 5xx or timeout
- Payment not processed (x402 payment required) — returns 402 if USDC payment not included
- Rate limit exceeded — returns 429
- Stale data if CoinGecko cache is delayed
