Developers · Scripts → API

Write the logic. Ship the API. Skip the service.

Script-2-API turns a Groovy or JavaScript snippet into a governed REST endpoint. The runtime sandboxes execution, applies platform controls, and gives you an OpenAPI spec for free.

The problem

Not every endpoint deserves a microservice.

A transform here, a calculation there, a small enrichment over a third-party API — none of these need a Docker image, a Helm chart, or a six-week onboarding to the platform. Apinizer's Script-2-API lets engineers drop a Groovy or JavaScript snippet into a governed runtime: same auth, same audit, same rate limits, none of the boilerplate.

Capabilities

What Apinizer does here

Groovy or JavaScript

Pick the language that fits the team. Both run inside a sandboxed runtime with the same lifecycle hooks.

Governed by default

Every Script-2-API endpoint inherits auth, rate limits, audit, and encryption — the same controls every other endpoint has.

OpenAPI generated

Declare parameters and response shape; OpenAPI ships automatically. Partners discover scripts the way they discover REST APIs.

Sandboxed runtime

Scripts run inside guardrails — no arbitrary filesystem, no unscoped network. Resources controlled by the platform.

Outbound to anything

Scripts can call upstream APIs, databases (via connectors), or message queues — through the same governed channels the gateway uses.

Audit captures the script

Every change to the script writes to audit. Auditor sees the version that ran, who deployed it, and the request that triggered it.

Use cases

In production, this looks like…

Banking
Istanbul bank ships 60 enrichment scripts in three weeks
Each script enriches a core-banking call with risk-score or KYC data. No new services; no container images; same audit posture as the legacy stack.
60 endpoints, 0 containers
Insurance
Frankfurt insurer wraps actuarial scripts as APIs
Groovy actuarial calculators that used to live in a spreadsheet are now governed endpoints. Auditor signs off because audit covers every call.
Public sector
Stockholm agency exposes simple lookups as JS endpoints
Junior engineers ship a new endpoint in one afternoon; the platform team only reviews policy, not boilerplate.
Retail
Madrid retailer transforms partner payloads with JS scripts
Each partner has slightly different field names. Script maps them; the downstream service sees a clean shape.
Telecom
Amsterdam carrier composes 3 backend calls into one customer view
Groovy script fans out to billing, network, and CRM; assembles the response. No new microservice; same auth and audit.
Media
Milan publisher A/B-tests a recommendation logic with scripts
Two scripts behind one endpoint; routing splits 50/50. New logic wins; promotion is one policy change.
Energy
Prague utility transforms SCADA payloads on the gateway
Tag mappings, unit conversions, and enrichment ship as scripts. SCADA team keeps its protocol; consumers get a clean API.
Government
Baku ministry handles partner-specific quirks via scripts
Each partner integration has its own normalization script. New partner onboarded in two days; previous version preserved in audit.
