# Kronos Trade Preflight – Pre-Trade Context Pack

> Kronos Trade Preflight – Pre-Trade Context Pack is a paid API for AI agents from kronossignals.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns a single-call pre-trade context bundle for a crypto asset, including derivatives state, recent liquidations, implied-volatility surface (BTC/ETH), and regime alerts, with per-component data-quality flags.

## 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 kronos-trade-preflight-pre-trade-context-pack-6eca7302
```

Example prompt: Before I open a long on BTC with a 4-hour horizon, pull the Kronos trade preflight — I want to see funding rates, open interest changes, recent liquidation prints, the IV surface, and any active regime alerts.

## When to prefer this

Choose this endpoint when you need a comprehensive pre-trade context bundle for a single crypto asset in one call rather than making four separate API calls to derivatives, liquidation, volatility, and regime-alert endpoints. It is especially valuable for agentic workflows where latency and cost efficiency matter, and where transparent data-quality flags (available/unavailable/stale per component) are required so the agent never acts on silently missing data.

## Known failure modes

- Asset not supported — only 16 specific slugs accepted; unrecognised slug returns an error
- Component marked 'unavailable' or 'stale' — individual data components may be flagged rather than returning stale values silently
- Payment failure — x402 payment of $0.05 USDC not processed correctly results in 402 response
- Invalid horizon or side enum value returns a validation error
- IV surface only available for BTC and ETH; other assets will have that component marked unavailable

## How this service works

Pre-trade context pack for one asset in a single call: derivatives state (funding, annualised funding, basis, open interest and its 1h change), recent liquidation prints, implied-volatility surface for BTC/ETH, and any active regime alerts. Replaces four separate paid calls. Each component is independently marked available, unavailable or stale — never flattened into a neutral claim. Facts and data quality only, no recommendation. $0.05 USDC.

## Output

A structured JSON bundle containing: derivatives state (funding rate, annualised funding, basis, open interest and 1h change), recent liquidation prints, implied-volatility surface (for BTC/ETH), active regime alerts, and per-component availability/staleness flags indicating data quality for each field.
