## 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 wickedapi-basis-spread-trading-data-endpoint-23ba4f4c
```

Example prompt: What's the current basis spread between BTC spot and futures right now? I want to see if there's a carry trade opportunity.

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to basis spread (spot vs futures differential) data for crypto or financial instruments, especially in agent workflows where micropayment via x402/USDC is preferred over subscription billing. It is well-suited for derivatives traders, carry trade bots, or arbitrage detection agents that need real-time or near-real-time basis figures without committing to a subscription.

## Known failure modes

- Missing or invalid query parameters may return empty data object
- x402 payment failure if USDC balance is insufficient
- Rate limiting or unauthorized access if API key is invalid or absent
- Service may return stale data if upstream market feed is delayed
- Generic 402 Payment Required response if payment header is not correctly formed

## How this service works

Agent-ready trading & market-data API: prices, indicators, prediction markets, macro, and an AI momentum score. Pay per call with x402 (USDC) or an API key.

## Output

Returns a JSON object with a `data` field containing basis spread figures (spot vs futures differential) and a `meta` field with a UTC timestamp. The specific basis metrics may include raw spread values, percentage differentials, or AI-enriched momentum context depending on the underlying data pipeline.
