# Cross-Border SLA Deadline Engine

Use this paid x402 API when an agent needs vendor-response SLAs, invoice-dispute windows, compliance remediation dates, or cross-border escalation deadlines. The price is $0.03 per successful request on Base (eip155:8453). No API key is required. An x402-capable client handles the initial HTTP 402 response, signs locally, then retries.
