When choosing Nano Banana Pro API service providers, developers often encounter quotes with huge price differences: some platforms claim "only 0.1 yuan per generation", while others quote 0.3-0.5 yuan. The core reason behind this price gap lies in different API sources—the former typically uses "reverse-engineered APIs" (simulating web operations through technical means), while the latter uses "official forwarding APIs" (directly connecting to Google Vertex AI platform). However, low-priced reverse-engineered APIs have serious problems such as watermarked generated images, unstable services, and inability to support high concurrency, which may bring unpredictable risks to business. This article will deeply compare two API sources across 12 dimensions including technical principles, stability, functional completeness, and compliance, helping developers understand essential differences and make technical choices that meet business needs.
What is Reverse API
Technical Principles of Reverse Engineering
Reverse API (Reverse Engineered API) refers to analyzing and simulating user operations of Google Gemini web version (gemini.google.com) through technical means, bypassing official API interfaces, directly calling web version services in an unofficial implementation. Its core technical process includes:
Browser Automation: Use headless browser tools such as Puppeteer and Selenium to simulate real users accessing gemini.google.com, automatically fill prompts and trigger image generation buttons.
Network Request Interception: Analyze web version HTTP/WebSocket communication protocols through packet capture tools (such as Charles, Fiddler), find API endpoints, request parameters, and response formats for image generation requests.
Cookie/Token Forgery: Extract web version authentication cookies or JWT tokens, reuse these credentials in backend services, bypassing official API Key authentication mechanisms.
Request Parameter Reverse Engineering: Analyze parameter encryption algorithms in JavaScript code, restore parameter structures used when web version submits image generation requests, including prompt encoding, resolution settings, style parameters, etc.
Response Parsing: Extract generated image URLs from HTML or JSON data returned by web version, encapsulate into response format similar to official API, provide services externally.
Typical Characteristics of Reverse API
No Google Cloud Account Required: Reverse API service providers do not need to apply for Google Cloud Platform accounts or Vertex AI permissions, can operate with only regular Google accounts.
Abnormally Low Price: Since bypassing Google's official billing system, reverse API costs only include server operating expenses and account maintenance costs, prices can be as low as 1/3 to 1/5 of official prices.
Limited Functionality: Constrained by web version functionality, reverse APIs usually cannot support all official API parameters, such as advanced style control, batch generation, asynchronous callbacks, and other enterprise-level features.
Instability: Google may update web version frontend code or verification mechanisms at any time, causing reverse APIs to suddenly fail, service providers need to frequently update reverse scripts to adapt to new versions.
⚠️ Technical Risk Warning: Reverse API is essentially unauthorized access to Google services, violating Google's Terms of Service. Developers and service providers using reverse APIs may face risks such as account bans and legal action. We strongly recommend accessing Nano Banana Pro services through compliant platforms using official Vertex AI resources such as APIYI apiyi.com, ensuring long-term business stability and legal compliance.
What is Official Forwarding API
Technical Architecture of Official API
Official Forwarding API (Official API Forwarding) refers to service providers applying for Google Cloud Platform accounts through formal channels, enabling Vertex AI services, using Google's official REST API interfaces to access Imagen 3 models, and providing relay services to customers based on this. Its technical architecture includes:
Google Cloud Enterprise Certification: Service providers need to complete Google Cloud enterprise certification process, provide company business licenses, tax information and other materials, bind international credit cards for billing.
Vertex AI API Authorization: Enable Vertex AI API in Google Cloud Console, create service accounts (Service Account) and generate API keys, obtain formal authorization to call Imagen 3 models.
Official SDK Integration: Use Google's official Python SDK (google-cloud-aiplatform), Node.js SDK, or directly call Vertex AI endpoints through REST API:
POST https://us-central1-aiplatform.googleapis.com/v1/projects/{PROJECT_ID}/locations/us-central1/publishers/google/models/imagen-3.0-generate-001:predict
Request Relay and Optimization: Service providers encapsulate unified interface formats based on official APIs, provide value-added services such as domestic network optimization, request queue management, error retries, billing statistics.
Compliant Billing Pass-through: Each API call is settled through Google's official billing system, service providers charge customers according to Google's actual pricing standards plus reasonable service fees.
Core Advantages of Official Forwarding API
100% Function Coverage: Supports all official parameters of Vertex AI Imagen 3, including advanced style control, image editing (inpainting/outpainting), negative prompts, seed value fixation, and other professional features.
