## How to call it through Zero

```

Example prompt: What's the next funding payment ETA and predicted rate for BTC perps on Binance right now — I'm deciding whether to enter before or after the next funding event.

## When to prefer this

Use this endpoint when you need real-time next-funding-event timing and rate prediction for a specific perpetual futures ticker on a named venue — particularly for entry/exit timing strategies that depend on funding arbitrage or cost avoidance. Prefer this over the cross-venue funding spread endpoint when you already know which venue you're trading on and want precise payment countdown data.

## Known failure modes

- Unsupported ticker or venue pair returns an error or empty result
- Stale or unavailable market data may produce inaccurate rate predictions
- Missing required input fields (ticker or venue) returns a 400-level error
- Rate limit exceeded or payment failure returns a 402/429 error

## How this service works

Next funding payment ETA for one crypto perpetual on one venue, with the current indicative funding rate alongside — when the next settlement lands and where the rate stands now. Entry-timing input for funding-arb and carry trades. Not a payment forecast: the endpoint takes no position side or size, and the rate can move before settlement.

## Output

Returns the estimated time until the next funding payment (ETA) and the predicted funding rate size for the specified ticker and venue, enabling entry timing decisions around funding events.
