Spend limits and alerts

Configure guardrails before allowing an agent to create paid Sessions.

curl -X PUT "https://api.nexalayer.net/v1/account/budget" \
  -H "X-API-Key: $NEXALAYER_API_KEY" \
  -H "Idempotency-Key: budget-2026-10-13" \
  -H "Content-Type: application/json" \
  -d '{"key_limit_usd":50,"daily_limit_usd":10,"pause_on_exceed":true,"alert_thresholds":[50,80,100]}'

GET /account/budget returns limits, estimated accepted spend, pause state, and the next UTC daily reset. GET /account/usage-alerts returns crossed thresholds. A purchase that would exceed a configured limit is rejected before provisioning; when pause_on_exceed is true the Key is paused for paid creation until its policy is updated with paused: false. Limits are safety controls, not a replacement for the billing ledger. Owners should still require approval for large or unusual purchases.
