## How to call it through Zero

```sh
zero fetch --capability coincap-macd-technical-analysis-8335a241
```

Example prompt: Can you pull the MACD technical indicator for bitcoin from CoinCap so I can see whether there's a bullish or bearish signal right now?

## When to prefer this

Use this endpoint when you need MACD technical analysis for a specific cryptocurrency asset without requiring a pre-registered API key — the x402 per-call USDC payment model on Base makes it ideal for autonomous agents that need on-demand technical indicator data. Prefer it over building your own MACD calculation when you want authoritative, pre-computed values from a trusted crypto data provider.

## Known failure modes

- Invalid or unknown asset slug returns an error or empty result
- Payment failure via x402 if USDC balance is insufficient or Base network is congested
- Rate limiting if API key quota is exceeded
- Network timeout for slow or unavailable upstream data

## How this service works

CoinCap gives AI agents, apps, and developers real-time cryptocurrency market data.

Two ways to access:
- **API key** — sign up at https://coincap.io and pass `Authorization: Bearer <key>` or `?apiKey=<key>`.
- **Keyless x402** (agents) — the 10 `agentFriendly` endpoints accept per-call USDC payment on Base via the [x402 protocol](https://x402.gitbook.io/x402). No signup needed. See `/.well-known/x402.json` for the machine-readable payment catalog.

## Output

Returns MACD technical indicator data for the specified cryptocurrency asset, including the MACD line, signal line, and histogram values used to assess trend direction and momentum
