x402 API Gateway for OpenClaw Bots: One Endpoint Replaces 18 API Keys

An x402 API gateway has been built to simplify OpenClaw bot configuration by replacing multiple API keys with a single endpoint. Instead of managing separate keys for services like Brave Search, Firecrawl, Google Maps, and LLM providers, developers can now use one gateway that handles authentication via USDC wallet credits.

Key Features and Services

The gateway provides access to 18 services without requiring individual API keys:

• Smart LLM Router: Multi-provider access to GPT-5, Claude Opus, Kimi K2.5, and Gemini Flash with auto-routing based on complexity. Simple questions go to fast/cheap models, while hard tasks use more powerful ones. It's OpenAI SDK-compatible—just set your base_url to the gateway.
• Web & Search: Brave Search with snippets and Firecrawl for site scraping.
• Maps & Navigation: Google Maps, Naver Maps, Kakao Maps, and TMap for places, geocoding, directions, and real-time traffic.
• Travel: Flight search with calendar pricing and route discovery, hotel search across 2M+ properties, and worldwide Airbnb listings.
• Food: Michelin Guide (Japan, Korea, USA) and Tabelog for Japanese restaurants.
• AI: ElevenLabs TTS for multilingual text-to-speech and Gemini Image Gen + Video (Veo 3.1 Fast).
• Finance & Data: DART for Korean corporate filings, Financial Modeling Prep for stock quotes, Korea Public Data Portal, and Court Auction for Korean property auctions.

Setup Process

Configuration requires three steps:

1. Go to clawy.pro and top up USDC credits (minimum $1)
2. Add the clawy-services skill to your bot—it auto-configures the gateway connection
3. For LLM routing specifically, point your bot's LLM config base URL at the gateway: base_url: https://x402.clawy.pro/v1/llm

No API keys are needed in your bot config. The gateway handles authentication via your wallet and deducts credits per token.

Why This Matters

Typical OpenClaw bot setups require 5-10 API keys for basic functionality, each representing a potential point of failure due to expiration, rate-limiting, or billing issues. With the gateway, configuration changes from multiple keys to a single endpoint:

base_url: https://x402.clawy.pro/v1/llm

You manage one balance and use one endpoint. If one provider goes down, the smart router automatically falls back to another.

Pricing

Most API calls cost fractions of a cent. LLM calls are per-token at actual provider cost plus 20% markup. A $1 top-up is sufficient for testing. Specific costs include:

• Brave Search: $0.006 per call
• Google Maps: $0.0036 per call
• Flight Search: $0.005 per call
• Hotel Search: $0.003 per call
• ElevenLabs TTS: $0.015 per call
• LLM (auto-routed): per-token + 30% markup
