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

> Delx Commerce — Bitcoin 5-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 2026-10-02).

Predicts whether Bitcoin's price will be higher or lower in the next 5 minutes, given a caller-supplied sequence of recent 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-bitcoin-5-minute-up-down-prediction-dfc92331 -d '<json body>'
```

Example prompt: Using my last 8 Bitcoin price ticks (timestamps and prices), tell me whether BTC is more likely to be up or down in the next 5 minutes and give me the probability for each direction.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call, no-signup Bitcoin short-term directional signal derived purely from your own supplied price observations. It is ideal for autonomous agents that already collect BTC price feeds and want a probabilistic up/down signal without integrating a full ML platform. Prefer it over general-purpose LLM reasoning about prices because it uses a dedicated model (delx-local-updown-v1) with a structured schema and explicit data quality scoring. Use it when a 5-minute horizon is the target window and you can supply at least 8 timestamped price points.

## Known failure modes

- Fewer than 8 price observations provided — request rejected due to minItems constraint
- Timestamps or prices outside allowed ranges cause schema validation errors
- Probabilities are explicitly marked as uncalibrated — model output may not reflect true market probability
- No live market data is used — results are based solely on caller-supplied prices, which are unverified
- Payment failure via x402 protocol results in 402 response and no prediction
- Data quality score may be low if observations are sparse or poorly spaced, reducing reliability of prediction

## 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'), associated probabilities (p_up and p_down summing to 1), a data quality score and label, model version metadata, the prediction horizon in minutes (5), and an array of warnings noting that probabilities are uncalibrated and results are not trading advice.
