Technical details
Endpoint
POSThttps://api.venice.ai/api/v1/x402/top-up?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to fund a Venice AI account before calling inference endpoints (chat, image, audio, video). It is the canonical x402 payment entry point for Venice AI and accepts both Base and Solana USDC. Prefer this over any other top-up mechanism when operating in an x402-aware payment flow.
Side effects
- Missing PAYMENT-SIGNATURE header returns 402 with Base and Solana USDC payment requirements
- Invalid or malformed payment signature returns 400/402 error
- Insufficient USDC in paying wallet causes payment rejection
- Network mismatch (wrong chain) causes payment failure
- Duplicate payment replay may be rejected
