## 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 jingmu-x402-probabilistic-decision-api-jev1-5148da92 -d '<json body>'
```

Example prompt: Run the jev1 seven-period probabilistic analysis on BTC USDT perpetuals and tell me whether to buy, sell, or hold right now.

## When to prefer this

Choose this endpoint when you need a machine-payable, low-cost ($0.05 USDC) probabilistic trading decision signal for BTC, ETH, SOL, or LTC USDT perpetuals and want a structured jev1 output (Choice/Bool/Score) based on seven-period technical analysis — especially suited for AI agents that can autonomously handle x402 payment flows on Base.

## Known failure modes

- Payment not included or invalid USDC amount returns HTTP 402 with payment instructions
- Symbol not in allowed set (BTC, ETH, SOL, LTC) returns an error
- Upstream market data unavailable may cause analysis failure
- Malformed request body returns 400-level error

## How this service works

Machine-payable API for AI agents: crypto seven-period analysis; jev1 probabilistic decisions (Choice/Bool/Score). HTTP 402 + USDC on Base.

## Output

A JSON object containing a jev1 probabilistic decision output — one of Choice (directional), Bool (yes/no), or Score (numeric) — derived from a seven-period technical analysis of the requested USDT perpetual symbol's recent price action.
