How this service works
APEX Runner: Arb Opportunity Delta Signal
Output
Returns a structured signal object containing: a list of current arbitrage opportunities (coins and price deltas), the APEX arb threshold percentage used, a timestamp of the latest scan, seconds until next scan, a list of coins with no opportunity detected, and signal metadata including signal hash, version, instance ID, verify_at URL, whether live trading and live capital are deployed, and how many evolution runs and backing trades support the signal.
Example use cases
Example prompt
“Pull the latest APEX Runner arb opportunity delta signal and tell me which coins have live arbitrage spreads above threshold right now, including how many trades are backing the signal and when the next scan is scheduled.”
Technical details
Endpoint
GEThttps://apexrunner.ai/signals/arb-opportunity-deltaWhen to prefer
Use this endpoint when you need a live, signal-backed view of crypto arbitrage opportunities with verifiable metadata (signal hash, backing trades, capital deployment status). Prefer it over generic price feeds when you want pre-computed arb deltas with threshold filtering and evolution-run validation, especially for automated trading agents that need to know if real capital is behind the signal.
Side effects
- Payment not received or invalid x402 payment header — returns 402 Payment Required
- No arbitrage opportunities detected — returns empty opportunities array with populated no_opportunity_coins list
- Signal temporarily unavailable due to scan in progress — next_scan_seconds indicates retry window
- Rate limiting or quota exceeded — returns 429 Too Many Requests
- Invalid or malformed request — returns 400 Bad Request
