# Kronos by ForgeMesh — Historical Market Signals

> Kronos by ForgeMesh — Historical Market Signals is a paid API for AI agents from kronos.forgemesh.io, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Retrieves historical crypto market intelligence signals including calibrated ranges, signal context, and risk state for autonomous agent decision-making.

## Facts

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 kronos-by-forgemesh-historical-market-signals-721b7179
```

Example prompt: Pull the last 96 hours of Kronos market intelligence signals for BTC/USD so I can audit which assets were flagged and what their signal scores looked like over that period.

## When to prefer this

Choose this endpoint when an AI agent needs a historical lookback of crypto market signals from Kronos for backtesting, decision auditing, or reconstructing past risk states. It is specifically suited for agents that have already integrated x402 micropayment flows on Base and need timestamped, calibrated signal history rather than real-time or live data.

## Known failure modes

- Missing or invalid 'hours' query parameter may return an empty signal array or a default lookback window
- x402 payment failure results in HTTP 402 response requiring USDC micropayment on Base before data is served
- Network or upstream data unavailability may return a 5xx error with no signal data
- Requesting an excessively large hours window may result in truncated results or timeout

## How this service works

Paid crypto market-intelligence API for autonomous agents. Calibrated ranges, signal context, risk state, decision journals, and outcome audits via x402 micropayments on Base.

## Output

Returns a JSON object containing a count of signals and an array of signal entries, each with a UTC timestamp, a list of top-k asset pairs (e.g. BTC/USD), and a signals map of asset pair to numeric signal score for that hour.
