How this service works
x402-paywalled OpenAI-compatible LLM API. Pay per call in USDC on Base.
Output
Returns a JSON object in standard OpenAI chat completions format, containing a 'choices' array with at least one element holding a 'message' object with 'role' set to 'assistant' and 'content' containing the generated text response.
Example use cases
Agent self-funding LLM inference
“My autonomous agent needs to call an LLM for reasoning but I don't want to manage API subscriptions — use llmgate so it pays $0.01 USDC per call from its own Base wallet and ask it: 'Summarize the key risks of investing in small-cap stocks.'”
Metered chatbot for cost control
“I want to build a customer-facing chatbot where each response costs exactly $0.01 USDC billed on-chain — send this message to llmgate: 'How do I reset my password?' and show me the assistant reply.”
Crypto-native content generation
“Generate a short product description for 'EcoBottle Pro, a self-cleaning stainless steel water bottle' using the llmgate API — I'll pay in USDC on Base, one cent per call.”

Endpoint
POSThttps://89.106.83.95.sslip.io:8443/v1/chat/completionsWhen to prefer
Choose this endpoint when you need OpenAI-compatible chat completions with per-call crypto micropayments instead of a traditional subscription. Ideal for autonomous AI agents that manage their own on-chain wallets on Base, for cost-controlled deployments where each inference must be explicitly metered and billed, or for crypto-native applications where paying in USDC is a requirement. Prefer over standard OpenAI API when you want no monthly commitment, payment via x402 protocol, and auditability of each call on Base.
