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 predicted directional lean ('up' or 'down'), probability estimates for both up and down directions (summing to 1.0), the model version used (delx-local-updown-v1), data quality score and label, number of observations used, horizon in minutes (15), and warnings (e.g. uncalibrated probability, not trading advice, caller-supplied prices not verified). The response schema is 'delx/prediction-updown-estimate/v1'.
Example use cases
Automated BTC trade signal generator
“I have 20 recent BTC price data points collected over the last hour, with the window open price at $68,200 and close timestamp at 1717205400. Can you tell me whether Bitcoin is leaning up or down for the next 15 minutes and how confident the model is?”
Real-time DeFi bot direction check
“Before my on-chain DeFi bot places its next BTC position, run a 15-minute up/down prediction using these 12 price observations — window open at $66,800, close timestamp 1717210000 — and return the probability it goes up.”
Backtesting prediction accuracy
“For my backtesting run, feed in these 8 historical BTC price observations with window open at $65,000 and close timestamp 1717100000, and get the model's up/down lean and probability so I can compare it to what actually happened.”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/bitcoin-up-down-15m?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call (no signup) short-term Bitcoin directional probability estimate using your own price data — especially useful for autonomous agents, trading bots, or backtesting workflows that already have recent BTC price observations and want a model-based signal without integrating a full market data subscription or managing API credentials.
Side effects
- Fewer than 8 observations supplied — minimum required for a valid estimate
- Invalid or out-of-range price values (below 1e-12 or above 1e15) — schema validation error
- Missing required observation fields (timestamp or price) — request rejected
- Window close timestamp not a valid Unix integer — validation failure
- Data quality too low — model may return low data quality score or degraded estimate
- Fee basis points outside 0–1000 range — schema validation error
