I Ran a 6-Check Probe on MonkeyCode's Free Server. Here's the Verdict.

Description and use

The author built a Python script that runs 30 requests for each of six checks—auth, throughput, latency, errors, concurrency, and structured output—against MonkeyCode’s free tier. The aggregated results informed whether to build on the free tier.

Problem

Free model endpoints often fail under real traffic, but demos don’t reveal these issues. Developers need a repeatable way to test free tiers before building on them.

Outcome

The probe revealed that MonkeyCode’s free tier could authenticate, list models, and return valid JSON, but had limited throughput and latency spikes under load. The data guided a cautious decision to use the tier with awareness of its constraints.

Workflow

• 1. Write a Python script using httpx and asyncio.
• 2. Define six checks: Auth, Throughput, Latency, Errors, Concurrency, Structured output.
• 3. Run the script from the same network as production (MonkeyCode’s free server).
• 4. Collect 30 calls per check, recording status codes, latency, and JSON validity.
• 5. Aggregate results into a table for comparison.
• 6. Use the table to decide whether to build on the free tier.

Evidence

Free tiers fail in predictable ways. Auth breaks. Latency spikes.

Source

Thirty calls per check. One script. One table at the end.
