LinkAPI Cheapest Plan 2026: Price Breakdown & Cost Calculator — Users who need access to many different models

The 30-second summary

In-depth review

GPT-4o input costs ¥2 per million tokens on LinkAPI’s cheapest channel, while Claude 3.5 Sonnet runs at ¥3 per million input tokens. That’s roughly 30-40% cheaper than OpenAI’s direct API pricing after the 2025 price cuts, but only if you use the lowest-tier routing.

Pricing Structure

LinkAPI offers two billing modes: pay-per-call and pay-per-token. Most developers will default to per-token since it matches direct API billing. The per-call option is fixed at ¥0.01 per request regardless of model — useful for simple classification tasks where you don’t want to calculate token burn.

The “premium” channels use direct routing to the model provider. The “cheapest” channels — which the platform defaults to — apply model dilution. That means your GPT-4o request might actually hit a smaller distilled variant or a fallback model if the main channel is overloaded. The price difference is real, but so is the quality drop.

The Dilution Problem

LinkAPI’s biggest draw is the ¥1 minimum recharge and daily check-in rewards (¥0.5-¥2 free credits per day). For a dev running a few dozen test queries, that’s practically free. But the cheap channels are unreliable. I’ve seen GPT-4o responses that were clearly GPT-4o-mini outputs — shorter, less nuanced, with the same token cost on my end. The platform doesn’t label which channel you hit unless you explicitly select “premium” in the API call.

If you need consistent model behavior (e.g., for production eval pipelines), always specify channel=premium in your request headers. That kills the cost advantage — premium GPT-4o is ¥5 input / ¥15 output, which is only 10% cheaper than OpenAI direct after the 2026 price reductions.

Hidden Fees and Batch Discounts

No batch discounts. LinkAPI charges the same per-token rate whether you send 1 request or 10,000. No monthly subscription tier either — it’s pure prepaid balance, with 支付宝 and 微信支付 accepted for top-ups.

The platform doesn’t charge extra for streaming or function calling, but the dilution issue applies there too. If you’re streaming from a diluted channel, you might see different tokenization or response cutoffs compared to the real model.

Pros & Cons

Pros

• ¥1 minimum recharge — lowest barrier I’ve seen for any relay station
• Daily check-in rewards effectively give you ¥15-¥60 free per month
• Both pay-per-token and pay-per-call billing cover different use cases
• 支付宝 and 微信支付 support for Chinese users

Cons

• Default cheapest channel dilutes model quality — you can’t trust it for production
• Premium channel pricing is only marginally cheaper than direct API
• 96% uptime is below average for relay stations (most competitors hit 98%+)
• No refund policy specified — balance is non-refundable once recharged

Verdict

LinkAPI is a decent budget option for experimentation and low-stakes prototyping where occasional model substitution is acceptable. The ¥1 minimum and daily rewards make it the cheapest way to test GPT-4o or Claude 3.5 Sonnet without a VPN. But for production workloads, the dilution risk and 96% uptime are dealbreakers. If you need reliable model identity and 99%+ uptime, look at platforms with dedicated channel routing and SLAs — you’ll pay more, but you won’t get a mini model masquerading as the full one.

FAQ

Q: Can I guarantee I get the real GPT-4o, not a diluted version? A: Yes — pass channel=premium in your API request headers. This forces direct routing to the full model, but costs roughly 2x the cheapest rate.

Q: Is there a free trial? A: No free trial. But the ¥1 minimum recharge plus daily check-in rewards (¥0.5-¥2/day) means you can run dozens of test queries for effectively ¥0.

Q: What happens if the cheapest channel is down? A: LinkAPI automatically falls back to another cheap channel, which may be a different model entirely. For critical requests, always use premium routing or implement your own fallback logic.
