For Agents

Compile and execute code snippets in over 70 languages and check remaining daily credit usage — without managing local runtimes.

Install Jentic One Beta

Connect the JDoodle Compiler API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the JDoodle Compiler API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

What an agent can do with JDoodle Compiler API.

Execute code in 70+ supported languages including Python, Java, C++, Go, and Rust

Pass standard input to a program run so test fixtures and sample inputs can be supplied

Pin a specific language version index for reproducible runs across requests

Use Cases

Patterns agents use JDoodle Compiler API for, with concrete tasks.

★ In-Product Code Execution

Embed runnable code snippets in documentation, tutorials, or LMS quizzes by sending the source to POST /execute and rendering the response inline. JDoodle handles compilation and runtime isolation, so the calling app does not need to maintain Docker images per language. Latency is typically sub-second for short scripts, which is acceptable for interactive learning experiences.

Call POST /execute with language 'python3', versionIndex '4', and the script 'print(sum(range(11)))', then return the output and CPU time.

Automated Code Sample Validation

Validate code samples in documentation pull requests by running each snippet against expected output before merge. CI scripts post each sample to /execute, compare the response to the expected stdout, and fail the build on mismatch. This keeps a body of tutorial code permanently green without provisioning a CI matrix per language.

Call POST /execute for each snippet in docs/, capture the output, and fail the job when the output does not match the expected fixture.

Credit Usage Monitoring

Track remaining daily compile credits to stay inside the JDoodle plan limit. POST /credit-spent returns the count of credits used so far in the current billing day; an agent can subtract this from the plan cap and surface a warning when the remaining budget is low. Useful for product teams that expose JDoodle to end-users.

Call POST /credit-spent and return the current spend; if it exceeds 90% of the daily cap, raise an alert to the operations channel.

AI Agent Code Execution Tool

An LLM-powered agent that writes code can use JDoodle through Jentic to run the snippet in a sandbox before presenting it to the user. Jentic exposes /execute as a discoverable tool so the agent picks it by intent — for instance 'run this Python code'. The clientId/clientSecret stay in the Jentic vault.

Search for 'execute a code snippet', load the POST /execute schema, and run the agent's generated Python solution to verify it produces the expected output before returning it to the user.

Key Endpoints

2 endpoints — the jdoodle compiler api runs source code in a hosted sandbox across more than 70 programming languages, returning the program output, cpu time, and memory used.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

JDoodle clientId and clientSecret are stored encrypted in the Jentic vault and merged into the request body at execution time, so the agent never holds either value directly.

Intent-based discovery

Agents search by intent such as 'run a Python snippet' and Jentic returns the POST /execute operation with its schema, so the agent supplies language, versionIndex, script, and stdin without reading the JDoodle docs.

Time to first call

Direct JDoodle integration: an hour or two for auth, language selection, and result parsing. Through Jentic: under 10 minutes — search, load schema, execute.

FAQs

Specific to using JDoodle Compiler API through Jentic.

What authentication does the JDoodle Compiler API use?

JDoodle uses a clientId and clientSecret pair, sent as fields inside the JSON body of each /execute and /credit-spent request rather than as a header. Through Jentic, both values are stored encrypted in the Jentic vault and merged into the request payload at execution time.

Which languages can I run with the JDoodle Compiler API?

JDoodle supports 70+ languages including Python (python3, python2), Java, C, C++, C#, Go, Rust, Node.js, Ruby, PHP, Kotlin, Swift, Scala, Haskell, R, and many others. Each language exposes one or more versionIndex values that pin the compiler or runtime version.

What are the rate limits and credit caps for the JDoodle API?

Each plan ships with a daily compile credit cap; the free tier is small (around 200 credits per day at time of writing) and paid tiers scale higher. Use POST /credit-spent to see current spend. There is no per-second rate limit in the spec, but throttle aggressive bursts to avoid 429 responses.

How do I run a code snippet in Python through Jentic?

Run pip install jentic, search for 'execute a code snippet', and Jentic returns the POST /execute operation. Load its schema, pass language='python3', versionIndex='4' (or your pinned version), the script string, and any stdin, then execute the call to receive the program output.

Is the JDoodle Compiler API free?

JDoodle has a free plan with a small daily credit cap and paid plans that scale credits and concurrency. Pricing is published on jdoodle.com. Each /execute call consumes one credit; /credit-spent itself is free and does not affect the daily count.

Can I pass standard input to my code with the JDoodle API?

Yes. POST /execute accepts a stdin field as part of the JSON body. Anything you place there is fed to the program as standard input, which is essential for sample-input style problems and for testing programs that call input() or read from stdin.
