How this service works
LLM inference API: OpenAI-compatible chat completions for 136 AI models (Claude, GPT, Gemini, Grok, DeepSeek, Qwen, Kimi, GLM), paid per call in USDC on Base with x402. No account, no API key, automatic refund if the model fails.
Output
Returns an OpenAI-compatible chat.completion JSON object containing the assistant's message text, finish reason (e.g. 'stop'), token usage counts (prompt, completion, total), model name, and a unique completion ID. If streaming is enabled, server-sent events are returned instead.
Example use cases
Agentic coding assistant with no key
“I want you to send my code snippet to DeepSeek Chat and ask it to find bugs and suggest fixes — pay for the call with USDC and give me back the response without me needing to set up any API account.”
Anonymous document summarization
“Summarize this 800-word article using DeepSeek Chat — keep it under 200 tokens and pay per call with USDC so I don't have to sign up anywhere.”
Autonomous chatbot with crypto micropayments
“Build me a customer support bot that uses DeepSeek Chat for replies, pays each inference call in USDC via x402, and automatically gets a refund if the model fails to respond.”
Technical details
Endpoint
POSThttps://modelaccessgateway.com/v1/chat/completions/deepseek%2Fdeepseek-chat?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need DeepSeek Chat specifically and want zero-friction access — no account signup, no API key management, and automatic per-call USDC billing on Base. Ideal for autonomous agents, ephemeral scripts, or privacy-conscious workflows where provisioning credentials is undesirable. Prefer this over OpenAI or Anthropic direct APIs when you want crypto-native micropayment billing with automatic refunds on failure.
Side effects
- Insufficient USDC balance triggers a 402 Payment Required before inference runs
- Model failure triggers automatic refund with no charge
- Invalid messages array (empty or missing role) returns a 400 validation error
- Exceeding max_tokens limit of 16384 results in a parameter error
- Network timeout on long completions may leave payment state ambiguous
