OpportunaOpportuna's answer:
Opportuna combines real-time data, multi-exchange coverage, and zero setup friction in one platform. Unlike competitors that require API keys or limit you to a few exchanges, Opportuna monitors 12+ exchanges out of the box with live updates. We also cover both spot arbitrage and funding rate arbitrage in a single dashboard, and offer a genuinely useful free tier - no credit card, no API setup, just open and start scanning.
Opportuna's answer:
Three reasons: (1) No API keys required. Works immediately without connecting your exchange accounts (2) Real-time data. Not delayed or historical snapshots (3) Free tier with full scanner access. You can validate the value before paying. Most competitors either paywall the scanner, require complex API setup, or show stale data. Opportuna is built for traders who want to find opportunities fast, not spend hours configuring tools.
