API MONETIZATION

Turn APIs and AI Into Revenue

Meter every API call, LLM token, and custom metric with sub-second accuracy. Automate billing with Moesif and enable developer self-service directly from your developer portal. All fully-integrated, out-of-the-box.

WSO2 Integrator architecture

Why it matters

APIs and AI products process billions of requests, yet most platforms force you to choose between custom metering code, bolted-on billing tools, or spreadsheets. WSO2 Monetization, powered by Moesif, gives users monetization capabilities that work directly with your gateway of choice, eliminating complex billing setups and reducing time to market.

Real-time metering of API and AI usage

Track API calls, LLM tokens, custom metrics, and MCP tool invocations with perfect accuracy. Any metric, monetized.

Flexible pricing models built in

Support pay-as-you-go, prepaid credits, tiered pricing, freemium, and subscription+overage without any custom code or changes in your application or API codebase.

Automated invoicing and revenue recognition

Usage data flows directly into Stripe, Zuora, or any other billing provider of your choice. Usage is metered, aggregated, and billing happens automatically with zero manual work.

Enable developer self-service

Embed dashboards into your customer and developer portals so customers can view consumption metrics in a single place and manage usage effectively.

WSO2 API Monetization eliminates the complexity of distributed billing tools and puts revenue operations directly on top of your existing infrastructure.

Key capabilities

Usage-based API billing

AI and LLM token monetization

Bill for LLM token consumption, MCP tool calls, and payload size directly in your API gateway. Track input tokens, output tokens, and cost attribution across OpenAI, Gemini, Claude, Azure OpenAI, Mistral, and AWS Bedrock.

SUPPORTS
  • Multi-model cost attribution for fallback and fan-out scenarios
  • Accurate billing when requests span multiple LLM providers
  • MCP tool call metering for AI agents consuming your APIs
  • Perfect accuracy in revenue split across AI infrastructure

Flexible pricing models

Deploy pay-as-you-go, prepaid credits, tiered pricing, freemium, and subscription+overage models out of the box. Automatically transition customers between tiers and trigger upgrade prompts when limits are reached.

  • Cohort analysis for targeted retention workflows

AI-driven analytics

Ask questions in plain language and get answers from your API data. Moesif's AI Explain surfaces patterns, anomalies, and root causes across traffic, latency, errors, and business metrics without requiring users to build a manual filter or query. One-click alerting and anomaly detection catch issues before customers report them.

HIGHLIGHTS
  • Conversational AI interface for querying API analytics and traces
  • Anomaly detection to identify unknown issues automatically
  • Real-time alerting via Slack, PagerDuty, or custom webhooks

Customer experience
