## 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 adh-altseason-index-signal-b4c9b2ad
```

Example prompt: What's the current altseason index — are we in altseason, bitcoin season, or neutral right now, and which top altcoins are outperforming BTC over the last 30 days?

## When to prefer this

Choose this endpoint when you need a single, pre-processed crypto market regime signal that aggregates 30-day performance across the top 50 non-stablecoin assets relative to BTC — ideal for agents that need a clean, labeled altseason/neutral/bitcoin-season classification without doing raw market-cap and return calculations themselves. It is especially useful for routing portfolio decisions, generating market briefings, or triggering regime-aware trading alerts at $0.05 USDC per call via x402 micropayment.

## Known failure modes

- Upstream data source unavailable — returns error or stale data
- Rate limiting or payment failure via x402 — returns 402 Payment Required
- Temporary service outage on agentdatum.com — returns 5xx error
- Data freshness lag if upstream aggregation pipeline is delayed
