Every language you will ever write, behind one key.
Polykey is a single authenticated endpoint over 2,500 catalogued language repositories. Look one up, generate a complete source file, or run it against its real toolchain — from any IDE, CI job, or agent.

curl -X POST https://polykey.net/api/functions/languageGateway \ -H "content-type: application/json" \ -d '{ "action": "resolve", "secret_key": "sk_live_••••", "query": "rust" }'

One POST. Your secret key in the body. Nothing else to install.
From zero to a running compiler in three steps.
Create an account
Sign up with email, Google, Microsoft, Facebook or Apple. One account covers every repository in the depository.
Activate and copy your keys
A flat $100 per month turns both keys on. The secret key is full access; the publishable key is read-only for browser clients.
Call the gateway
POST one endpoint from anywhere — your editor, a build pipeline, an agent. Look up a repository, generate a file, or execute it.
A depository, a compiler, and a model behind one door.
One key, every repository
2,500 catalogued languages and pathways behind a single bearer secret. No per-language accounts, no SDK roulette.
Real execution, not a mock
Send source and stdin; the gateway runs it against that language's actual toolchain and returns stdout, stderr and exit code.
AI that writes whole files
Ask for a program in any catalogued language and get a complete file with its run command, not a fragment to stitch together.
Unicode-safe end to end
Identifiers, emoji, combining marks and right-to-left text survive the wire intact, with a documented support tier per language.
A curriculum per language
Rules, worked examples and guided steps live beside each repository, so the gateway doubles as the manual.
Read-only key for browsers
Ship catalog lookups from a client app without exposing your secret. Both keys stop working the moment the plan does.
The whole platform is one HTTP call.
POST a JSON body with an action and your key. The catalog, the compiler and the model all sit behind it, so there is nothing to install and nothing per-language to configure.
Search the depository and get repository metadata. Works with both keys.
Produce a complete source file plus the command that runs it. Secret key only.
Compile and run source against the real toolchain, with stdin support. Secret key only.

One price. No metering games.
Polykey is a paid gateway with no trial, and no per-call billing either. Pay for the month, use it as hard as you like, cancel whenever you want — access runs to the end of the period you already paid for.
