A provider incident should never
be a storefront incident.
Smart routing fails over to a backup model the instant a provider degrades, autoscaling absorbs the spike, and per-surface budgets keep AI spend predictable from Black Friday to a quiet Tuesday.

Route. Detect. Retry. The customer never sees it.
The gateway monitors every provider endpoint. When one degrades or errors, the request retries on a configured backup model — no code change, no manual cutover, no war room. Weighted load balancing spreads traffic across deployments so no single endpoint is a bottleneck under peak load.
- Fallback chains retry on a backup model on error or timeout
- Routing strategies: cost, latency, weighted
- Per-key RPM/TPM caps stop one surface from starving another
- Every routing and failover decision captured in observability

Cost control at volume
Costs settled from the provider response — exact, not estimated. Per-surface budgets for catalog vs. search vs. support.
Observability per surface
Latency and error-rate breakdowns per model and key, exported to Langfuse, Datadog, or S3 — see a degradation before a customer does.
Guardrails for shopper data
Prompt-injection detection and PII redaction on support assistants, where customers paste order and contact details.
What we can promise on reliability and data.
- 99.9% uptime SLA on every tier, backed by managed autoscaling infrastructure — failover is automatic, not a runbook.
- Shopper data is protected by PII-redaction guardrails and a configurable data policy — useful for support assistants where customers paste order and contact details.
- SOC 2 Type II is in progress (target Q3 2026); payments run through Stripe (PCI DSS Level 1) so Nemo Router never touches card data.

Retail questions, answered
What happens to our storefront if a model provider goes down?
Fallback chains retry the request on a backup model automatically. Because Nemo Router routes across the whole catalog, a single provider incident does not take down recommendations, search, or support — the request fails over and the customer never sees it.
How do we keep AI spend predictable during peak season?
Costs are settled from the provider-reported response, so spend is exact rather than estimated. Give each storefront surface — recommendations, search, support — its own budgeted team. Soft caps fire Slack alerts at 70%, 90%, and 100%; a hard cap returns 402 so a runaway loop during a sale cannot blow the budget.
Can the gateway handle Black Friday traffic?
The gateway runs on managed autoscaling infrastructure (Google Cloud Run) and adds a low, predictable p50 overhead. Per-key RPM/TPM caps protect a shared provider pool from one surface starving another. For very large committed volume, an Enterprise plan adds dedicated capacity and a residency pin.
Do we have to manage provider API keys?
No. Nemo Router is a fully managed gateway — your services authenticate with Nemo Router virtual keys only, and we manage every provider relationship. One key, one bill, and the platform fee is lower than OpenRouter at 5.5% (4% / 2% / 0% by tier).
Ship storefront AI that survives the spike.
