Discover
Marketplace that feels like a product, not a directory.
Search by capability, endpoint, vendor, or category. Compare plans, latency, availability, and community ratings. Every listing is a real, live API product.

Build the API
business.
Run it from
one surface.
FastRestful gives every API product a marketplace, a release pipeline, a metered gateway, subscriptions, billing, documentation, and an operator control plane — without stitching five disconnected tools together.

One system / 02
The whole API business, in one operating surface.
Not a landing page with a dashboard bolted on. FastRestful connects the public catalog, the release boundary, the gateway, the money, and the people operating it.
Release
Release discipline by default.
Import OpenAPI, reconcile endpoints, diff breaking changes, stage docs, and promote immutable releases. The release boundary is the product boundary.

A tester, a key vault, and a usage ledger in one flow.
Subscribe, issue scoped credentials, test live endpoints through the metered gateway, and inspect redacted request history without exposing upstream secrets.

Operate
Consumer console, vendor studio, staff control plane.
Three purpose-built surfaces over the same tenant model: consumers manage access and spend, vendors run their portfolio, staff run the platform.
Monetize
Turn usage into revenue.
Plans, trials, coupons, overage billing, invoices, refunds, payouts, and platform subscriptions share the same ledger — with provider events reconciled once.
- Stripe, PayPal, Flutterwave, Paystack, and Razorpay
- Signed webhook settlement, never browser redirects
- Stripe Connect and PayPal payout reconciliation
Govern
Operate with evidence.
Permission-aware admin, append-only audit, moderation and appeals, webhook delivery receipts, maintenance mode, and health probes. Every consequential action leaves a trail.
Two-factor adoption ENFORCED
Webhook receipts IDEMPOTENT
Audit stream APPEND-ONLY
Three surfaces / 03
Built for every seat at the table.
The same product data, permissions, and billing state — shaped for consumers, vendors, and platform operators.
For API consumers
From discovery to first call in minutes.
Find an API, compare plans, subscribe, create an application, issue a key, and send a live request. Usage, invoices, and support stay attached to the same workspace.
- API explorer with secure gateway testing
- Applications, key scopes, rotation, and revocation
- Subscriptions, quotas, spend, and invoices
- Request logs, analytics, support, and safety center
For API vendors
Run an API portfolio, not a spreadsheet.
Create products, import contracts, manage endpoint docs, publish releases, inspect consumers, issue refunds, and reconcile payouts from one tenant-scoped workbench.
- Product lifecycle and publication readiness
- OpenAPI import, endpoint docs, release notes, diffs
- Consumer health, request logs, and support threads
- Plans, coupons, invoices, refunds, and payouts
For platform operators
One control plane for the platform itself.
Watch traffic, review vendors, manage plans and gateways, publish content, run campaigns, configure locales, and resolve safety cases — all permission-scoped.
- Operational snapshot and decision queues
- Site settings, CMS, navigation, custom assets
- Newsletter studio, banners, short links, media
- Moderation, appeals, enforcement, audit export
Control plane / 04
Control without a second stack.
Release discipline, money movement, and governance are first-class workflows — not conventions your team has to remember.
One live invariant.
Promote a release only when the OpenAPI contract and endpoint catalog match. Live specs are immutable; the previous live version retires in the same transaction.
- OpenAPI 3.x / Swagger 2.0 import
- Breaking-change reports
- Endpoint policy preservation
- Plan entitlement carry-forward
Every cent has a state.
Provider webhooks settle invoices and subscriptions. Refunds reserve funds before retrying. Payouts move through a monotonic state machine with an audit trail.
- Trials, coupons, overage, tax-ready lines
- Cumulative partial refunds
- Stripe Connect + PayPal transfers
- Immutable ledger entries
Permission-aware by construction.
Tenant isolation is enforced server-side. API keys are hashed and encrypted. Staff actions are permission-scoped and audited. Sensitive data stays out of public serializers.
- Roles: owner, admin, developer, billing, viewer
- 2FA, OIDC, SAML, invites
- Append-only audit + export jobs
- Maintenance and health probes
Operating models / 05
Three ways to run the same system.
Start with the surface your team needs first. The catalog, gateway, billing, and control plane are already connected.
01 / Marketplace
Open your marketplace.
Approve vendors, publish products, split payouts, and keep discovery, identity, and policy on one platform.
02 / First-party API
Sell your own API.
Version the contract, meter requests, bill subscriptions, support customers, and publish docs without a second stack.
03 / Internal platform
Govern internal APIs.
Give teams a scoped catalog, keys, logs, and docs while platform operators keep policy and audit in one place.
Capability atlas / 06
Surface area without the sprawl.
Every capability shares the same tenant model, permissions, design tokens, and event history. Expand a category to see what ships in the box.

Documentation / 07
From first request to production deploy.
Install locally, configure every integration, deploy with PostgreSQL and Redis, harden the gateway, and operate the platform with confidence.

Ready when you are
Put your API business on one surface.
Start locally with SQLite and seeded data. Move to PostgreSQL, Redis, object storage, and your payment providers when you are ready. FastRestful is designed to make that transition boring.
