Use Cases

1. Protecting LLM API Spend

Your AI agents call GPT-4 thousands of times a day. One bug = one $10K bill. Fairvisor enforces token-based rate limits and cost budgets in real time.

2. Stopping Agentic Loops

AI agents get stuck in loops — requesting the same thing over and over. Fairvisor detects these patterns and stops them before they drain your budget.

3. Multi-Tenant API Rate Limiting

You run a B2B API with Free, Pro, and Enterprise tiers. Fairvisor enforces per-tenant rate limits from JWT claims — no code in your services.

4. Noisy Neighbor Isolation

One tenant’s traffic spike shouldn’t affect your other customers. Fairvisor isolates each tenant with independent counters and budgets.

5. Emergency Abuse Response

A tenant is causing a cascade failure. Kill-switch provides rapid, role-gated containment with full audit trail.

6. Safe Policy Rollouts

Test new rate limits on production traffic without blocking anyone. Shadow mode shows you what would happen. Then flip the switch when you’re confident.

7. AI Cost Attribution for FinOps

Which team is spending the most on LLM calls? Which endpoint? Which model? Fairvisor tracks cost by your business dimensions and exports to CSV.

8. Blocking AI Crawlers

GPTBot, ClaudeBot, and Meta-ExternalAgent can generate large crawler volumes. Fairvisor detects AI crawlers by User-Agent pattern matching and enforces rate limits — so they get predictable throttling instead of unlimited access to your content.

9. Compliance & Audit Trail

SOC 2 auditors want to see rate limiting controls, change management, and incident response. Fairvisor provides immutable audit logs, policy versioning, and kill-switch records.

10. Anti-Extraction for LLM APIs

Attackers can run high-volume prompt harvesting campaigns to reproduce model behavior. Fairvisor combines token/cost quotas, identity-aware policy, extraction-focused anomaly signals, and edge enforcement playbooks (throttle, tarpit, block) to reduce risk and raise attack cost.

11. ASN-Aware Crawler Segmentation

Not all crawler traffic is the same. Fairvisor supports policy segmentation by ip:type, ip:asn, and ua:bot_category, so you can apply stricter limits to non-residential/content networks and different limits by crawler class. Apply separate ISP vs Hosting limits with a single policy update.

12. Partner API Contract Enforcement

Each integration partner gets contract-aligned limits (rate, burst, and budget) with explicit escalation actions. Fairvisor enforces those contracts at the edge so breaches become controlled 429/throttle behavior instead of backend incidents.
