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 carrylens-perpetuals-funding-radar-27e43da6
```

Example prompt: Scan cross-venue perp funding rates for a $10,000 position held for 168 hours with 20 bps total costs, and show me the top carry spread opportunities ranked by net annualized yield.

## When to prefer this

Choose this endpoint when you need a live, cost-adjusted ranking of cross-venue perpetual funding carry spreads across multiple crypto exchanges in a single call — especially when you want break-even analysis and net yield projections already computed for a given notional, holding period, and cost budget, without needing to aggregate and normalize raw funding rate feeds yourself. Prefer it over raw exchange APIs when you need ready-to-act carry trade signals with execution-tier classification.

## Known failure modes

- Invalid notionalUsd format (non-numeric string) returns a 400 validation error
- holdingHours outside the 1–2160 range may return empty or erroneous results
- totalCostBps above 2000 may filter out all opportunities, returning an empty spreads array
- Payment failure via x402 protocol results in a 402 response and no data returned
- Stale funding data if upstream venue feeds are delayed may produce inaccurate spread projections
- Network timeout to Netlify-hosted endpoint possible under high load

## How this service works

Live, cost-aware cross-venue perpetual-funding screens for trading agents. x402 payment; no API key or account.

## Output

Returns a ranked list of top cross-venue carry spread opportunities, each with the long venue, short venue, coin, gross annualized spread, projected net yield percent, projected net funding in USD, assumed total cost, break-even hours, execution tier, and cost screen status — plus the assumptions used and a liquidity floor summary showing screened market count and Hyperliquid volume/OI figures.
