## 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 tanod-chainpeek-cross-venue-perpetual-funding-carry-ranker-1a10595e -d '<json body>'
```

Example prompt: Show me the top 10 cross-venue funding rate arb opportunities for BTC and ETH across Binance, Bybit, and OKX, assuming a 7-day hold and 3 bps taker fee per side — sort by annualized spread.

## When to prefer this

Use this endpoint when an agent needs to identify, rank, and compute net APR for cross-venue perpetual funding carry trades across the five major venues (Binance, Bybit, OKX, Hyperliquid, dYdX). It is the right choice when fee-adjusted annualized spread is the primary decision metric and the agent needs structured long/short venue pair recommendations per asset rather than raw funding rate feeds from a single exchange.

## Known failure modes

- Symbol listed on fewer than two chosen venues returns asset in symbols_not_found rather than markets
- A venue's API is temporarily unavailable and appears in venues_failed with an empty result for that venue
- min_volume_usd filter too high causes all venue legs to be excluded, returning empty markets array
- Invalid symbol pattern (non-alphanumeric or too long) causes 422 validation error
- Requesting fewer than two venues returns a validation error since arbitrage requires at least two venues
- Funding rates are point-in-time snapshots and may not reflect the actual settled rate

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns a ranked list of perpetual funding arbitrage pairs, each specifying the optimal long and short venue, current funding rates (hourly and annualized), 24h volume, open interest, spread annualized percent, net annualized percent after fees, and mark/index prices — sorted by spread descending by default.
