How this service works
Machine-readable market intelligence for onchain agents, served over x402.

Example use cases
Example prompt
“Using the fold x402 Gemini 3.5 Flash endpoint, send this message thread and ask: 'What are the current trends in onchain DeFi liquidity?' — temperature 0.7, max 512 tokens, and pay the $2 USDC per-call fee via x402.”
Technical details
Endpoint
POSThttps://x402.fold.computer/llm/gemini-3-5-flashWhen to prefer
Use this endpoint when you need LLM inference that is natively payable via the x402 USDC micropayment protocol — especially for onchain agents that lack traditional API keys and instead transact with crypto. Prefer this over standard LLM APIs when your agent needs to pay per-call without a subscription, or when you want Gemini 3.5 Flash responses embedded in an x402-compatible agentic workflow.
Side effects
- Payment not provided or insufficient USDC — x402 payment required error returned
- Malformed messages array (not OpenAI format) — validation error
- Model unavailable or rate-limited upstream from Gemini — 5xx error
- Invalid temperature or max_tokens values — parameter validation error
- x402 facilitator or payment channel failure — payment processing error
