Delx Commerce — Ethereum 30-Minute Up/Down Price Prediction
x402
Delx Commerce — Ethereum 30-Minute Up/Down Price 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).
Given a sequence of Ethereum price observations, returns a probabilistic up/down prediction for the next 30 minutes using a local model.

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 containing: the predicted directional lean ('up' or 'down'), probability of upward movement (p_up) and downward movement (p_down) summing to 1, the model version and metadata flags (uncalibrated, deterministic), a data quality label and score, the number of observations used, and a list of warnings such as 'not_trading_advice' and 'probability_is_uncalibrated'.
Example use cases
DeFi bot pre-trade directional check
“I have 8 recent ETH price ticks from the last 10 minutes starting at $2,980 and ending at $3,010 — can you give me a probability estimate for whether ETH will be up or down 30 minutes from now before I execute this trade?”
Automated crypto dashboard signal
“Every 15 minutes, take the last 20 ETH price observations and tell me the probability it goes up or down over the next 30 minutes so I can display a directional signal on my dashboard.”
Backtesting directional model accuracy
“I have a set of historical Ethereum price windows with 12 observations each and a known window open price — run each through the 30-minute up/down estimator and return the predicted lean and p_up so I can compare against actual outcomes.”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/ethereum-up-down-30m?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call, no-signup probabilistic directional forecast for Ethereum over a 30-minute horizon, powered entirely by caller-supplied price data without requiring any external market data feed. It is ideal for autonomous agents that already have price history and want a structured probability estimate with explicit uncertainty warnings, and when verifiable micropayment delivery via x402/USDC is required. Avoid it when you need calibrated trading signals, live market data integration, or forecasts for assets other than ETH.
Side effects
- Fewer than 8 observations provided — request rejected, minItems constraint violated
- Price values outside allowed range (below 1e-12 or above 1e15) — validation error
- Uncalibrated probabilities: model explicitly warns output may not reflect true market probabilities
- No live market data used — predictions are based solely on caller-supplied prices, not verified
- Low data quality score if observations are sparse or cover a short time window
