The API Billing Gap

Your API is in production. Customers are using it. But you're batch-processing logs with cron jobs and hoping nothing gets lost.

THE HOMEGROWN TRAP
# Cron job runs every hour...
0 * * * * /scripts/aggregate-logs.sh

# Parse nginx access logs
grep "200 OK" /var/log/api.log \
  | awk '{print $7}' \
  | sort | uniq -c > /tmp/usage.csv

# Manually import into billing spreadsheet
# Hope no events were dropped
# Pray the timezone math is correct
REAL-TIME EVENT STREAMING
curl -X POST https://api.aforo.io/v1/events \
  -H "Authorization: Bearer sk_live_..." \
  -d '{
    "tenant_id": "cust_884",
    "metric": "api_compute_ms",
    "value": 145,
    "idempotency_key": "txn_009912"
  }'

# Sub-ms ingestion. Idempotent.
# Aggregated. Rated. Invoiced.
# Automatically.

Idempotency keys guarantee exactly-once billing. No double charges. No lost events.

Built for Companies That Already Have APIs

Your API is in production. Your customers are using it. Billing is the missing piece.

DevTools

Developer Tool Companies

Twilio, SendGrid, Stripe. Free tier leaks money, enterprise tier is manual billing. Aforo auto-tiers transitions, enforces usage caps, and sends real-time overage alerts.

SaaS

SaaS Companies Adding APIs

Product wants to launch an API. Billing team says six months. With Aforo, launch API billing in days. Customers self-serve. No billing team involvement.

AI / Data

Data & AI API Providers

Clearbit, ZoomInfo, Replicate. Every customer needs custom pricing. Per-customer rate plans with volume discounts auto-applied and white-labeled invoices.

CFO

Revenue Leakage Prevention

Every unbilled API call is lost margin. Aforo's guaranteed-delivery Kafka pipeline ensures every event is captured, rated, and settled. Zero leakage.

CTO

Native Gateway Plugins

Drop-in plugins for Kong, Apigee, AWS API Gateway, Azure APIM, and MuleSoft. Meter at the edge without adding blocking calls to your critical path.

CPO

M:N Metric Composition

Don't just charge per call. Price based on compute time, payload size, or regional routing — without asking engineering for schema changes.

How It Works

Four steps from gateway to invoice. No custom middleware. No batch scripts.

1
Connect Your Gateway
Deploy the Aforo metering plugin (Kong, AWS, Apigee, Azure, or MuleSoft). The plugin starts tracking every API call — method, endpoint, customer, timestamp. Zero code changes.
2
Define Your Metrics
API calls, bandwidth, processing time, storage — whatever you want to charge for. Each metric becomes a billing dimension. Independent, composable, auditable.
3
Build Your Pricing
Use the pricing studio. $0.01 per call for the first 10K, $0.005 after. Graduated pricing. Volume tiers. The UI updates pricing visually as you change rates.
4
Customers See Their Bill
Itemized invoices generated automatically at period end. 47.2K API calls at graduated rates = $382. 12 GB bandwidth at $0.10 = $1.20. Payment reconciles. Done.

The Billing Pipeline

From gateway event to paid invoice. Every step automated, auditable, and idempotent.

Gateway Event
POST /api/v1/search — 145ms compute, cust_abc
Idempotent Ingestion
Dedup by txn_009912, validated, queued to Kafka
Aggregation Window
Hourly rollup: 47,200 calls, 12.5 GB bandwidth
Pricing Engine
Graduated: 10K × $0.01 + 37.2K × $0.005 = $286
Invoice Generated
INV-2026-0042 — $383.65 — auto-sent to customer

Built-in Safeguards

Monetized APIs are revenue. Aforo watches for the edge cases that break billing.

Protection

Deletion Guard

Can't delete a monetized API with active subscriptions or unpaid invoices. Prevents revenue loss from accidental deletions.

Monitoring

Drift Detection

Detects when a monetized API disappears from your gateway. Alerts within 24 hours with remediation steps and root cause.

Governance

Automatic Tagging

Aforo tags every monetized API in your gateway. Deny policies prevent unauthorized changes. Tags auto-remove when subscriptions end.
