API Monetization

Turn your API into
a revenue engine.

Send Monigo a usage event on every API call. We meter it, generate invoices, and charge customers through Paystack or Flutterwave — automatically. No billing engineers required.

One integration

Add billing to your API in under an hour

No SDKs to rip out. No proxy layer to add. Just fire one extra event after each billable request — Monigo does the rest.

✓ Works with any API — REST, GraphQL, gRPC
✓ TypeScript + Go SDKs available
✓ Handles retries and duplicate events automatically
✓ No changes to your existing auth or rate-limiting

api-handler.ts

// Your existing API handler
export async function POST(req: Request) {
  // ... your existing logic ...
  const result = await runModel(req.body)

  // Add this: fire a usage event
  await monigo.events.ingest({
    events: [{
      event_name: 'api_call',
      customer_id: req.user.id,
      idempotency_key: req.headers['x-request-id'],
      properties: { tokens: result.usage.total },
    }]
  })

  return result
}

Pricing Models

Any API pricing model, zero code

Configure your billing rules in the dashboard. Change them any time without redeploying.

Per-call billing

Simplest

₦0.50 per request

Charge a fixed amount for each API request. Transparent, predictable, easy to explain to customers.

Token-based billing

AI/LLM APIs

₦2.00 per 1,000 tokens

Bill per token, per word, or per compute unit. Standard for AI/ML APIs where cost scales with processing.

Tiered pricing

Growth-friendly

First 10k free → ₦0.40 → ₦0.20

Lower rates at higher volumes. Encourages customers to use more while you protect margins at low volumes.

Hard cap / prepaid

Enterprise

₦50,000 for 200k calls

Sell a block of API calls upfront. When depleted, meter usage or pause the customer until they top up.

Built for production API billing

Sub-100ms event ingestion

Monigo's ingest endpoint responds in under 100ms — never the bottleneck in your API response chain.

Idempotent by design

Pass an idempotency key with each event. Replay your entire event log without double-billing anyone.

Bring your own payment keys

Charges go through your Paystack or Flutterwave account. Your money, your relationships.

Real-time usage dashboard

See live per-customer consumption. Set alerts at 80% quota. Know who is about to churn before they do.

API monetization questions

What is API monetization?

API monetization is the process of generating revenue from an API product. This typically means charging developers or businesses based on their API usage — per call, per token, per result, or through tiered subscription plans.

How do I bill customers for API usage in Nigeria?

Use Monigo to ingest a usage event every time your API is called. Monigo meters the calls, applies your pricing rules (per-call, tiered, or capped), generates an invoice, and charges the customer through Paystack or Flutterwave — all automatically.

What API pricing models does Monigo support?

Monigo supports per-call pricing, token-based pricing (e.g. per 1,000 tokens for AI APIs), tiered pricing, volume discounts, hard caps, and hybrid flat-fee-plus-overage models.

Do I need to change my API to use Monigo?

No. Your API stays unchanged. You add one SDK call (or HTTP request) to your existing request handler to send a usage event to Monigo after each billable API call. It takes less than an hour to integrate.

Stop building billing. Start shipping features.

Most platforms spend weeks building billing logic that should take hours. Monigo gives you that time back — and keeps giving it back every billing cycle.
