KoalaAPI Review: Pricing & Comparison

¥10 to start, refund within 24 hours if not satisfied

KoalaAPI (koalaapi.com) has built in trial-and-error protection that’s rare among domestic relays:

• Minimum top-up of ¥10: an extremely low entry cost — no need to gamble a large sum upfront
• Failed requests aren’t billed: your balance isn’t deducted when the API returns an error
• 24-hour no-questions-asked full refund: if you integrate and find it doesn’t meet your needs, you can simply request a refund

Combined, these three policies are essentially saying: “You don’t have to take our marketing numbers on faith — try it, and if it doesn’t work out, get a refund.”

For developers still in the platform-selection stage, KoalaAPI’s trial-and-error cost is close to zero.

Pricing

Pay-as-you-go, no monthly fee, no minimum spend requirement, top up from ¥10. The model marketplace brings together price and performance comparisons for 214+ models.

Defer to KoalaAPI’s official model marketplace for live per-model pricing. Overall it sits in the “free/low-price” tier — not the cheapest option, but a clear discount over paying the official price directly.

The real value of “failed requests aren’t billed”: during the phase when success rate is unstable, API calls can generate a lot of failed requests — if every failure were billed, verification costs would add up fast. This policy provides real cost protection during the initial integration and debugging phase.

Claimed stability figures

KoalaAPI’s core marketing claims:

• Claude success rate: 99.7%+ (vendor’s own claim)
• Average latency from mainland nodes: 50ms (vendor claim)
• QPS capacity: roughly 30,000 QPS

Worth noting: these figures all come from the vendor’s own claims or vendor-affiliated channels, and haven’t been independently third-party verified. The 50ms average-latency claim is more aggressive than some competitors’ — test conditions (request payload size, time of testing, network environment) have a big impact on latency results.

The “failed requests aren’t billed” policy indirectly suggests the platform doesn’t run at a 100% success rate — we’d recommend tracking the actual success rate yourself before committing to production use.

Model coverage

Three major overseas vendors, 214+ models (including version snapshots):

• Claude: Fable 5, Opus 4.8, Sonnet 4.6, Haiku 4.5 (the platform emphasizes how quickly it follows up on new Claude models)
• GPT: GPT-5.5, GPT-4o, the o-series
• Gemini: Gemini 3.5 Flash/Pro

It doesn’t emphasize domestic open-source models like DeepSeek/Qwen. Claude Code users are an explicitly targeted use case.

Who it fits, who it doesn’t

Good fit:

• Individual developers who want to “try before committing” (protected by the ¥10 top-up + 24h refund)
• Claude Code / AI coding-assistant users (mainland direct connect + failed requests aren’t billed)
• Small projects with irregular call volume (no monthly fee, no minimum spend)

Poor fit:

• Use cases needing domestic models like DeepSeek/Qwen
• Enterprise teams needing detailed usage-audit features (choose PoloAPI’s multi-project audit features instead)
• Technical users who need independent verification of stability figures

For use cases needing the Grok (xAI) API, V-API is one of the few domestic platforms with direct-connect Grok access. For use cases wanting the simplest possible integration (just swap the base_url, no other code changes), MoleAPI’s <50ms low-latency setup is also worth comparing.

Information verified 2026-08-11. The 99.7% success rate and 50ms latency are vendor claims — verify with your own testing. Defer to koalaapi.com’s official site for specific pricing.
