DMXAPI

Still worrying about the trouble of recharging overseas big model API and unstable access? Enterprises need to collaborate with multiple models but are stuck with high costs, the emergence of DMXAPI (big model API) accurately solves these pain points – as the intelligent aggregation platform launched by LangChain, it takes “unified interface + low price discount + domestic adaptation” as the core. With “unified interface + low price discount + domestic adaptation” as the core, it integrates 300+ mainstream big models around the world, supports WeChat Alipay recharge, and no scientific Internet access, so that developers and enterprises can make one-stop calls to GPT-5, Claude 4.5 and other top models at a 6-7% discount, making it the price-performance choice for domestic AI development in 2025. This article combines the latest functionality of the actual test and official information to dismantle its core advantages, practical points and application value, to help you unlock the efficient model call with zero threshold.

First, the core positioning of DMXAPI: “multi-model call transfer station” for domestic developers.

The core mission of DMXAPI is to “lower the threshold of AI model use”, its name comes from the initial letters of “big model”, and its positioning can be summarized as “an efficient tool for three types of users”. The positioning can be summarized as “an efficient tool for three types of users”:

• Individual developers: no need for overseas bank cards, you can test the top models and validate project prototypes at zero cost by charging as little as $1;
• Small and medium-sized enterprises (SMEs): Reduce 60%+ calling cost through the original factory procurement discount, and unified interface to avoid the tediousness of multi-model adaptation;
• Domestic teams: no special network settings, stable access to overseas models, while enjoying 7×24 hours Chinese customer service support.

Different from OpenRouter’s “global model aggregation” and SiliconFlow’s “reasoning acceleration focus”, DMXAPI’s core advantage is “domestic friendly + cost-effective + service”. Attentive” – focusing on the payment, access, after-sales pain points of domestic users, while keeping the model update speed in sync with the original factory, as of November 2025, it has covered the whole scenario of text, multimodal, graphic and video, and has become the first choice of API tools in the fields of e-commerce, customer service, and programming.

Second, the core function of the actual test: 5 highlights, reconstruction of multi-model calling experience

1. 300+ models full coverage: real-time synchronization of the latest global models.

The model library of DMXAPI is continuously expanding, so it can meet diversified needs without switching platforms and synchronize with the new models of the original manufacturers in the first time:

• Top closed-source models: GPT-5 (including Pro version, with full mathematical reasoning and programming ability), Claude 4.5 Sonnet/Opus, Gemini 2.5 Pro.
• Domestic mainstream models: Qwen 3-VL (multimodal visual understanding), DeepSeek-V3.2 (160k long contexts), GLM-4.6 (355B parameters, domestic model benchmark);;
• Featured Functional Models: DeepSeek-OCR ($0.02/time, 20x compression efficiency), Minimax M2 (programming exclusive, 204k context), Kolors Raw Graph (1 second to produce graphs);;
• Speech Video Model: Minimax Speech 2.5 (supports 40 languages, tone reproduction natural), Cosy Voice 2 (100ms fast speech generation).

The platform is categorized and filtered by “text/multimodal/graphics/speech”, so that novices can directly select the model according to the scenario, without having to test the adaptability one by one.

2. Domestic friendly adaptation: no threshold for payment and access.

This is the advantage of DMXAPI for domestic users, and the testing process is simple and unobstructed:

• Charging method: support WeChat, Alipay direct recharge, the minimum 1 yuan to start charging, overseas users can contact the manual recharge, no need for virtual card or overseas bank card;
• Access experience: no need for scientific Internet access in the country, distributed server deployment, call GPT-4o average delay of only 200ms, stability is better than similar overseas platforms.
• Privilege unlocking: recharge a minimum of 5 yuan (about 1 U.S. dollar) to upgrade VIP, unlock all the models to use privileges, free users can experience the basic model.

Compared with the complex recharge process of the original API, DMXAPI allows domestic users to “get started with one key”, and the recharge will arrive instantly without extra handling fee.

3. Unified interface + low-code access: 3 lines of code to switch all models.

DMXAPI is fully compatible with OpenAI API format, and the access cost is very low:

1. Get the exclusive API Key in the “Workbench-Token” page after registration.
2. Change the base URL of the original OpenAI code to ;https://www.dmxapi.cn/v1/
3. Modify the model parameters (e.g. “claude-4.5-sonnet”, “qwen-3-vl”), no other adjustments are needed. gpt-5

For example, the code of calling Claude 4.5 is identical to GPT-5, and switching models only requires modifying the logo. After a SaaS company uses it, the multi-model access cycle is shortened from 10 days to 1 day, and the development efficiency is improved by 90%. The platform also provides three alternative Base URLs to adapt to different development tools and avoid 404 error reporting.

4. Cost-effective + cost-controllable: 60% off the original price

DMXAPI removes the intermediate links through cooperation with model manufacturers and has a significant cost advantage:

• Price discounts: mainstream models as low as 60% off, call GPT-5 cost savings of 40% compared to the original factory, DeepSeek-V3.2 price dropped by 50%.
• Cost: Kolors generates diagrams in 1 second, the cost is 66% lower than the industry average, e-commerce platforms can save 2/3 of the expenditure on batch generation of commodity diagrams;
• Usage management: support for setting the token amount by project, log page can view the Token consumption details of a single call, you can also set the balance of the warning to avoid accidental overspending.

Enterprise-level customers can also enjoy exclusive discounts, the average cost of hosting the model is reduced by another 52%, taking into account the flexibility and economy.

5. Security Compliance + Considerate Service: Data Security is Guaranteed

DMXAPI has outstanding performance in security and service, and has been tested to meet the needs of domestic use:

• Data security: only Token consumption logs are retained, user interaction content is not stored, and SM4 encryption and Level 3 authentication are supported, which makes the use of sensitive scenarios more assured.
• High concurrency support: through dynamic routing algorithms, it can cope with 30,000 requests per minute, and it is not easy to get stuck in high-flow scenarios, and it can also automatically switch to the backup model;
• After-sales support: 7 × 24 hours Chinese customer service, to provide one-on-one technical advice, from the interface configuration to the model selection of the whole guide, novice can also quickly troubleshooting.

Typical application scenarios: covering the entire industry AI development needs
