# Delx Commerce — Ethereum Up/Down 5-Minute Prediction

> Delx Commerce — Ethereum Up/Down 5-Minute Prediction is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).

Predicts whether Ethereum's price will be up or down over the next 5 minutes, given caller-supplied historical price observations

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 delx-commerce-ethereum-up-down-5-minute-prediction-e3ddca54 -d '<json body>'
```

Example prompt: Using my last 10 ETH price observations — timestamps and prices from the past hour — predict whether Ethereum will be up or down over the next 5 minutes, and give me the probability for each direction.

## When to prefer this

Use this endpoint when you need a fast, stateless, pay-per-call ETH 5-minute price direction estimate using your own historical price data — no account, no API key, just USDC on Base or Solana via x402. Prefer this over ML model hosting or subscription APIs when you want verifiable pay-per-result inference for short-horizon crypto direction classification without managing infrastructure. Not suitable as a standalone trading signal — treat output as probabilistic estimate with calibration caveats.

## Known failure modes

- Fewer than 8 price observations provided — request rejected (minItems:8)
- Invalid timestamps (non-integer or below minimum) — schema validation error
- Price values out of allowed range (below 1e-12 or above 1e15) — schema validation error
- Payment failure or insufficient USDC balance — 402 payment required response
- Uncalibrated probabilities: model warns results may not be well-calibrated for live trading
- Data quality may be flagged as poor if observations are sparse or irregularly spaced

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object with: the directional lean ('up' or 'down'), probability of price going up (p_up) and down (p_down) over the next 5 minutes, model metadata (version, calibration caveats), data quality score and label, schema version, status ('estimate'), and an array of warnings such as 'probability_is_uncalibrated' and 'not_trading_advice'. The result is deterministic for identical inputs.
