## 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 swaphunt-market-dominance-a3d86976
```

Example prompt: What's Bitcoin's current dominance of the total crypto market cap, and how much is Ethereum holding — I want to see if capital is sitting in the majors or starting to rotate into alts.

## When to prefer this

Use this endpoint when you need a quick, low-cost read on the overall crypto market structure — specifically BTC and ETH dominance as a percentage of total market cap. Prefer this over generic price feeds when the goal is gauging capital concentration in majors vs altcoins, or setting up context before querying the /alt-season endpoint for a more targeted rotation signal.

## Known failure modes

- Payment not included or invalid — endpoint requires $0.001 USDC x402 payment header
- Data temporarily stale if upstream market data provider is delayed beyond the ~5 min refresh window
- Rate limit or service unavailability returning 5xx
- Malformed request returning 400 if query params are incorrectly structured

## How this service works

BTC and ETH market-cap dominance (% of total crypto market cap), plus total market cap and active-coin count, refreshed every ~5 min. Use to gauge whether capital sits in majors vs alts. For the alt-rotation read specifically, use /alt-season.

## Output

Returns BTC dominance (% of total crypto market cap), ETH dominance (%), total crypto market cap value, and count of active coins — data refreshed approximately every 5 minutes, suitable for assessing whether the market is in a bitcoin-led or altcoin-rotation regime.
