API revenue
visibility, finally.
Ledger Gate turns x402 observability events into clear business insights — revenue per endpoint, paid vs unpaid ratios, latency trends, and drill-down analytics, all in one place.
Turning API endpoints into business insights
An x402 monetized API observability platform
Real-time Tracking
Capture every request and response with microsecond precision. Monitor your APIs in real-time and never miss a beat.
Analyze and visualize
Use our powerful analytics engine to uncover trends, patterns, and insights from your API data. Aggregate data and visualize it with customizable dashboards and charts.
Track Revenue and Performance
Go beyond just monitoring API calls. Track the revenue generated by each endpoint and identify your most valuable APIs at a glance.
Everything you need to understand your API
From raw events to actionable business insights — ingest, aggregate, and visualize your x402 API traffic in one place.
Revenue Visibility
Track revenue generated per endpoint, over time, and across your entire API surface. Know which APIs make your business money — at a glance.
Privacy First
We store only metadata — never private keys, wallet addresses, or raw transaction data. Read-only payment references keep your users safe.
- No private keys stored
- No transaction submission
- Read-only payment references
SDK Event Ingestion
Drop our lightweight SDK into your API gateway and start streaming observability events instantly. Minimal overhead, maximum insight.
Usage Analytics
Requests per endpoint, paid vs. unpaid ratios, and traffic patterns — all aggregated and ready to explore.
Real-time Tracking
Capture every request and response with microsecond precision. Events are ingested, aggregated, and surfaced in your dashboard in seconds.
Reliability Monitoring
Track failed payments and latency trends over time. Catch degradations before they become outages.
Endpoint Drill-Down
Zoom into any individual endpoint to see its full activity history, recent paid requests, and revenue contribution.
Transparent pricing, coming soon.
Pricing tiers are actively being planned and worked on. While we finalise the details, the event ingestion API operates under a temporary rate limit on the free tier. Paid tiers will unlock higher limits, longer retention, and priority support.
Temporary rate limits in effect
The event ingestion API is currently rate-limited while pricing and infrastructure tiers are being designed. These limits will be lifted or adjusted when paid tiers launch. All existing data and accounts will carry forward.
