# Kronos x402 Market Digest API

> Kronos x402 Market Digest API is a paid API for AI agents from kronossignals.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Returns a structured market intelligence digest for a specified crypto asset, including regime classification, calibrated upside probability, funding rate, basis, volatility, and fear-greed index, delivered via x402 micropayment.

## 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-x402-market-digest-api-b3e4d9e5
```

Example prompt: Pull the Kronos market digest for BTC and tell me the current regime, calibrated 24-hour upside probability, funding rate interpretation, and overall thesis.

## When to prefer this

Choose this endpoint when you need a compact, multi-signal market intelligence summary for a specific crypto asset in a single call — combining regime, sentiment, derivatives signals, and a calibrated ML probability — rather than querying each signal type individually. Prefer it over raw price or forecast endpoints when you want an interpretive digest with a human-readable thesis and driver explanations ready for downstream reasoning or display.

## Known failure modes

- Invalid or unsupported asset slug returns an error — only the ~16 supported slugs (btc, eth, sol, bnb, xrp, etc.) are valid
- Payment not completed via x402 results in 402 Payment Required response before data is returned
- Network or upstream data source outage may cause stale or unavailable digest
- Misconfigured x402 wallet or insufficient USDC balance blocks access

## Output

A JSON object containing: asset identifier, timestamp, market regime label (e.g. breakout, squeeze), a human-readable thesis paragraph, calibrated and raw upside probability over 24h, a list of named market drivers (funding rate, basis, realized vol, fear-greed, model probability) each with value and interpretation, caveats, disclaimer, and a reference link to the full forecast endpoint.
