# Delx Commerce — Bitcoin 15-Minute Up/Down Prediction

> Delx Commerce — Bitcoin 15-Minute Up/Down Prediction is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).

Predicts whether Bitcoin price will go up or down over the next 15 minutes, given caller-supplied price observations.

## 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-bitcoin-15-minute-up-down-prediction-37c730f3 -d '<json body>'
```

Example prompt: Using the last 8 Bitcoin price observations I'm about to give you — with the window opening at $67,500 and closing at timestamp 1717200000 — predict whether BTC will go up or down over the next 15 minutes and give me the probability for each direction.

## When to prefer this

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.

## Known failure modes

- 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

## 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'.
