How this service works
Chat completions for GPT-5.6, DeepSeek V4 and Gemini behind one OpenAI-shaped endpoint. No account, no API key: the request pays for itself in USDC on Base, Polygon, Arbitrum or Solana. Pay with the upto scheme and only what you actually use settles - the unused ceiling comes back.
Output
A chat completion response following the OpenAI-compatible format, containing the assistant's generated text message, model used, token usage counts (prompt, completion, total), and finish reason.
Example use cases
Keyless LLM access for agent pipelines
“I need to call gemini-3.5-flash-lite through DexL to get a one-paragraph explanation of quantum entanglement — keep it under 150 tokens and use a temperature of 0.7, and pay per call so I don't have to manage API keys.”
Automated content drafting with micropayments
“Use DexL's gateway with gemini-3.7-flash to draft a professional email declining a meeting request, keeping the output under 300 tokens — I want to pay per use without setting up an account.”
Multi-model comparison via single endpoint
“Run the same prompt — 'What are three ways to reduce household energy consumption?' — through both gemini-3.5-flash and gemini-3.6-flash on DexL, limit each to 200 tokens, so I can compare their outputs without separate API keys.”
Technical details
Endpoint
POSThttps://agents.dexl.io/v1/chat/completionsWhen to prefer
Choose this endpoint when you need to access Gemini models without managing API keys or accounts, especially in machine-to-machine or agent workflows where x402 micropayment-per-call billing is preferred over subscription plans. Ideal for serverless agents, one-off inference calls, or multi-tenant systems where per-request cost attribution matters.
Side effects
- Payment not received or x402 payment rejected — request blocked before inference
- Requested model name not in enum (gemini-3.6-flash, gemini-3.7-flash, gemini-3.5-flash, gemini-3.5-flash-lite) — validation error
- max_tokens not specified or set too high — quote computation fails or request rejected
- Upstream Gemini model unavailable or rate-limited — gateway returns 5xx error
- Malformed messages array — request rejected with schema validation error
