How this service works
Bitcoin Up or Down 30-Minute Probability estimates p_up and p_down for half-hour windows using the widest caller-supplied context in this family. Send 8-240 ordered caller-supplied BTC price observations, the target venue's opening price, and its close timestamp; optionally include UP/DOWN share prices and entry fees for a descriptive model-edge comparison. Returns a conservative probability pair, lean, input-quality score, model contract, and warnings for $0.003 USDC via x402 on Base or Solana…
Output
Returns a JSON object with: asset (BTC), schema version, status (estimate), an estimate object with p_up, p_down, and lean direction (up/down), a data_quality object with label, score, and number of observations used, model metadata including version and calibration warnings, a list of warnings (e.g. uncalibrated probability, not trading advice), and horizon_minutes (30). Optionally includes a descriptive model-edge comparison when market share prices and fees are provided.
Example use cases
Binary options edge check before entry
“I have 20 ordered BTC price observations from the last 25 minutes, the venue open price is $95,400, the window closes at Unix timestamp 1748710800, the market is pricing up shares at 0.60 and down shares at 0.40 with a 30 bps fee — can you tell me if the model sees an edge and which direction it leans?”
Automated 30-minute BTC signal generation
“Every 30 minutes I want you to take my 8 most recent BTC price data points, with the current venue open price and the upcoming close timestamp, and compute a fresh up/down probability estimate so I can decide whether to act on the next window.”
Data quality check on BTC price feed
“I want to know if my BTC price observation series — 15 data points over the last 28 minutes — is high enough quality to rely on for a 30-minute direction prediction; the venue open is $96,800 and the close timestamp is 1748715600.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/bitcoin-up-down-30mWhen to prefer
Choose this endpoint when you need a conservative, model-driven directional probability estimate for Bitcoin over a 30-minute window using your own caller-supplied price data — especially when you want to compare against binary market implied odds with an explicit edge calculation. It is preferable when you have 8–240 ordered BTC price observations ready and need a fast, deterministic, reproducible estimate without relying on live market data feeds. Not suitable for longer horizons, other assets, or when a calibrated probabilistic forecast is required.
Side effects
- Fewer than 8 observations provided — request rejected with validation error
- Observations not ordered by timestamp — may reduce data quality score or trigger warnings
- window_open_price or window_close_timestamp missing — endpoint may return degraded estimate or error
- market_up_price + market_down_price do not sum near 1.0 — edge comparison may be misleading
- Probability is uncalibrated by design — always returns warning that output is not trading advice
- Payment failure via x402 on Base or Solana — request not processed
- More than 240 observations provided — schema validation error
