Technical details
Endpoint
POSThttps://merchant.payai.network/api/v1/keys/vend?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically purchase and provision a new PayAI API key funded with a specific USD-denominated credit balance in a single atomic call, especially in agentic or automated workflows that need fresh credentials on demand. Prefer this over manual dashboard key creation when operating in agent pipelines that require self-funded API access.
Side effects
- Insufficient USDC payment — payment of exactly $1 USDC per call is required via x402 protocol
- Invalid amount format — query param must match pattern ^\d+(\.\d{1,2})?$
- Invalid recovery email format — must match standard email pattern
- Key name too long — maximum 64 characters
- Payment not confirmed — USDC transaction may fail or timeout
- Missing required fields — type, method, bodyType, and body must all be present
