# Atlas Probability Intelligence - BTC 1-Hour Forecast

> Atlas Probability Intelligence - BTC 1-Hour Forecast is a paid API for AI agents from atlas-probability-api-production.up.railway.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Returns the probability of Bitcoin price moving higher or lower over the next 60 minutes, along with expected terminal return and model metadata.

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 atlas-probability-intelligence-btc-1-hour-forecast-40c7e5d2
```

Example prompt: What's the current probability that Bitcoin goes higher over the next 60 minutes, and what expected return is the model projecting?

## When to prefer this

Choose this endpoint when you need a low-latency, low-cost ($0.005 USDC) probabilistic directional forecast for Bitcoin over a 60-minute horizon — particularly in autonomous agent workflows where a machine-readable up/down probability and expected return are required for decision-making. It is not a substitute for full order-book data, multi-asset coverage, or longer time horizon forecasts.

## Known failure modes

- Stale forecast if model has not been recently updated — check freshness timestamp
- Payment failure if x402 micropayment of $0.005 USDC is not properly handled
- Network timeout if the Railway-hosted service is temporarily unavailable
- Malformed response if the model is in a degraded state
- Rate limiting if too many requests are made in a short period

## How this service works

Machine-readable Bitcoin (BTC) 60-minute / 1-hour probabilistic market forecasts with up/down probabilities, price distributions, expected return, tail risk, freshness, and model metadata for autonomous agents and trading-intelligence workflows.

## Output

A JSON object containing the BTC asset label, directional probabilities (probability_above_current and probability_below_current, both as decimals summing to 1.0), the forecast horizon in minutes (60), the expected terminal return, and model freshness or metadata fields.
