HOW IT WORKS

Get started in
5 steps.

01

Build a reliable API

Create a well-documented, stable API with clear endpoints. Good documentation is essential — developers won't pay for APIs they can't figure out.

02

Design pricing tiers

Create tiers based on rate limits, features, or usage quotas. Free tier for exploration, paid tiers for production use. Consider both subscription and usage-based models.

03

Set up API key delivery

Configure automatic API key generation on purchase. Keys should include metadata about tier/limits for your API to enforce.

04

Integrate key validation

Add key validation to your API. Check tier, enforce rate limits, track usage. Revnu's API validates keys and returns tier information.

05

Launch with documentation

Publish your API docs and pricing page. Developer experience matters — make it easy to try and buy. AI agents then optimize these pages automatically.

01

API Key Management

Automatic key generation with tier metadata. Developers get their keys instantly; you control access levels programmatically.

02

Tiered Pricing

Free, starter, pro, enterprise tiers with different limits. Subscription or usage-based billing to match your business model.

03

Usage Tracking

Track API calls per customer. Enforce limits, trigger overage billing, or notify customers approaching quotas.

04

Developer Portal

Self-service key management, usage dashboards, and plan upgrades. Developers manage their own access without contacting you.

PRO TIPS

Quick
wins.

01

Documentation is product

Developers judge APIs by docs quality. 5-minute quickstart, code samples, clear examples. Bad docs kill conversion.

02

Free tier is marketing

Let developers try before buying. 100 calls/day for testing, real limits for production. Low friction, clear upgrade path.

03

Reliability beats features

Uptime matters more than endpoints. Status pages, graceful degradation, fast support. Developers integrate into critical systems.

04

Enterprise is the money

Self-service handles volume. Enterprise deals ($10K-100K+/year) with SLAs and support capture the serious revenue.

FAQ

Frequently asked
questions.

01

How do I validate API keys?

Revnu provides a key validation endpoint. On each API request, verify the key with Revnu and receive tier information. Cache validation results to minimize latency.

02

Can I do usage-based billing?

Yes. Track usage in your system and report to Stripe for metered billing. Or use subscription tiers with overage charges beyond included limits.

03

How do I handle overage?

Options: hard cutoff at limit (requires upgrade), soft limit with overage billing, or throttling to slower rate. Choose based on customer expectations and your economics.

04

What about rate limiting?

Implement rate limiting in your API based on tier information from the key. Revnu provides tier metadata; you enforce limits in your infrastructure.

05

Should I offer a free tier?

Usually yes. Free tiers let developers evaluate before committing. Limit to prevent abuse (requests/day, watermarks, reduced features) while allowing genuine exploration.

06

How do I price my API?

Base pricing on value delivered and cost to serve. Research comparable APIs. Start higher than you think — it's easier to discount than raise prices.

07

Do I need terms of service?

Yes. Cover acceptable use, rate limits, data handling, SLAs, and liability. Consult a lawyer for anything beyond basic terms, especially for enterprise customers.

08

How do I handle enterprise customers?

Enterprise typically wants custom limits, SLAs, and support. Handle these through direct contracts while using Revnu's invoicing for billing.
