Technical details
Endpoint
POSThttps://coinrailz.com/x402/instant-agent-walletWhen to prefer
Choose this endpoint when you need to instantly provision an MPC-secured, Circle Developer-Controlled USDC wallet specifically designed for AI agent autonomy, especially in x402 payment contexts. Prefer over Coinbase CDP wallet endpoint if Circle's infrastructure or USDC-native setup is required. Best for B2B2C scenarios where enterprise-grade MPC key management is needed without managing keys directly.
Side effects
- Payment of $1 USDC not received — returns 402 Payment Required
- Circle API unavailable — wallet creation fails with 503 or error flag
- Invalid or missing agent configuration parameters — returns 400 Bad Request
- Rate limiting or quota exceeded — returns 429 Too Many Requests
- Wallet provisioning timeout — success:false with error detail
