> EventEdge Oracle - Market Pulse is a paid API for AI agents from edge.arakelproof.space, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-17).

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 eventedge-oracle-market-pulse-21b9460a
```

Example prompt: Pull the current market pulse from EventEdge Oracle and show me a cross-market comparison of probabilities for the top active prediction markets — no trades, just the data.

## When to prefer this

Choose this endpoint when you need a read-only, machine-readable snapshot of prediction market conditions across multiple platforms simultaneously, without any risk of executing a trade. It is ideal for analytics pipelines, monitoring agents, dashboards, and arbitrage detection that require structured comparison data. Prefer it over exchange APIs when cross-market aggregation and comparison — rather than order placement — is the primary goal.

## Known failure modes

- Missing or malformed 'properties' query parameter may return an empty or error response
- Payment failure (x402) if USDC balance is insufficient — returns 402 Payment Required
- Stale data if upstream market feeds are delayed — check 'generated_at' timestamp
- Rate limiting if too many calls are made in a short period
- Unknown market identifiers may return empty result sets rather than an error

## How this service works

Machine-readable prediction-market monitoring and cross-market comparison. No trade execution.

## Output

Returns a JSON snapshot labeled with schema version 'eventedge.market-pulse.v1' and a generation timestamp, containing cross-market comparison data for active prediction markets. The response explicitly confirms no trade execution occurred and includes machine-readable probability and market metadata fields.
