Every capability built for mission-critical AI.
Tanvelo proxies traffic between your applications and 147+ AI providers. If an upstream service experiences an outage or rate limit, requests fail over in sub-180ms. Budget ceilings prevent runaway loops, and conversation text is never stored on disk.
How Tanvelo handles every in-flight call
A high-availability proxy layer engineered to eliminate upstream failure modes without adding latency or storing user prompt text.
Unified Ingress
Call our OpenAI-compatible endpoint or official TypeScript/Python SDK. Route to any of 147+ AI models without disparate client libraries.
Governance & Limits
Atomic Redis token-buckets enforce RPM/TPM limits, verify monthly spend caps, and stream responses in volatile memory.
Automated Failover
If an upstream provider returns 429 throttling or a 5xx crash, Tanvelo immediately catches it and completes via your backup model in sub-180ms.
Explore All Capabilities
Showing 21 capabilities across failover routing, security, spend control, and developer tooling.
Core Architectural Capabilities
10 core featuresAutomatic Outage Backup (Instant Failover)
Zero downtime during AI provider rate limits & crashes
If an AI service like OpenAI or Claude slows down, crashes, or is overloaded, Tanvelo automatically switches your app to a backup AI model in less than a quarter of a second.
147+ AI Models in One Account
Universal access to OpenAI, Claude, Gemini, Groq, DeepSeek & more
Access every major foundation model through a single OpenAI-compatible standard. Switch models or add providers in seconds without rewriting code.
Connect Any Custom or Private AI
Plug in internal company servers, Ollama, vLLM, or custom models
Route internal models running in your private data center or VPC alongside cloud providers with identical failover, rate limiting, and observability.
Sanitized Inspection & 10-Day Auto-Purge
Debug requests with in-flight secret redaction and automated TTL purge
Inspect sanitized request and response bodies in your dashboard for debugging. Credentials and auth tokens are redacted in flight, and bodies are permanently purged after 10 days.
Encrypted Credential Vault (AES-256-GCM)
Authenticated encryption at rest protects all provider API keys
Provider API keys are encrypted at rest with server-side authenticated ciphers and decrypted strictly in memory during outbound dispatch.
Hard Monthly Budget Ceilings ($ USD)
Automated circuit-breakers prevent unexpected billing spikes
Set strict dollar-denominated spend caps per project or API key. Once reached, requests are safely cut off before excess costs accrue.
Atomic Distributed Rate Limiting
Token-bucket rate enforcement backed by Redis Lua scripts
Enforce requests-per-minute (RPM) and tokens-per-minute (TPM) across distributed instances with zero race conditions.
1-Line Drop-in Migration
Compatible with official OpenAI SDKs and agentic frameworks
Point your existing OpenAI SDK baseURL to Tanvelo. No prompt refactoring or code rewrites required.
Official TypeScript & Python SDKs
First-party client libraries with native typing and streaming
Native SDKs published on npm and PyPI featuring built-in retries, automatic backoff, and full TypeScript typing.
Real-Time Telemetry & Latency Metrics
Sub-millisecond tracking across every provider and model
Track response latency, HTTP status codes, and tokens across providers to identify performance bottlenecks.
Developer Controls & Governance
11 capabilitiesActive Circuit Breakers & Health Probing
Automatically fast-fails distressed upstream providers
When an AI provider suffers consecutive latency spikes or errors, Tanvelo trips an active circuit breaker to redirect traffic and safely probes for recovery.
Deterministic Routing Cascades
Strictly ordered priority chains with zero black-box surprises
Tanvelo follows your exact fallback sequence in order. We never use opaque algorithms to route your traffic unpredictably.
Instant Model Hot-Swapping
Update primary and fallback models without redeploying code
Change default models and fallback sequences in real time directly from the console or API without application rebuilds.
Cryptographic Gateway Keys (SHA-256)
Single-reveal credentials stored exclusively as irreversible hashes
Tanvelo gateway keys (tv_live_...) are displayed once upon generation. Only salted cryptographic hashes are retained in the database.
SSRF & Private Network Isolation
Protects internal cloud infrastructure from malicious traversal
Strict endpoint URL validation blocks Server-Side Request Forgery (SSRF) and insulates cloud metadata services.
Micro-Dollar Cost Telemetry
Real-time cost tracking split across prompt and completion tokens
Calculates exact cost per request in real time using updated official pricing schedules for all 147+ providers.
0% Token Markup (Direct Provider Billing)
Pay exact wholesale prices directly to upstream model providers
Tanvelo never marks up token prices or tacks on per-token platform fees. You pay providers directly at standard rates.
Real-Time Server-Sent Events (SSE)
Low-latency token streaming with seamless failover switching
Stream tokens back to client browsers with zero buffering. If primary model fails before emitting tokens, fallback stream engages automatically.
HMAC-SHA256 Webhook Notifications
Event-driven alerts for budget thresholds, rate limits, and outages
Receive signed notifications for budget thresholds, rate limit triggers, and failover events with automatic retries.
Sanitized Request Inspector
Debug headers, status codes, and token splits per request
Audit individual requests in the console with full visibility into provider choices, token splits, and latency.
Real-Time Gateway Health & Status
Public status indicators backed by a 99.99% uptime target
Continuous gateway engine health monitoring visible across console footers and public status endpoints.
Direct Provider Calling vs. Tanvelo Gateway
Evaluate how Tanvelo protects mission-critical production pipelines without changing your prompt structure or marking up token prices.
| Scenario | Direct Provider Connection | With Tanvelo Gateway |
|---|---|---|
Provider Outages & Rate Limits Upstream 429 or 5xx server downtime | Applications freeze or crash. Users see broken error screens and workflows break. | Sub-180ms automatic failover to designated backup models. Client streams never drop. |
Privacy & Data Retention Confidential customer conversations | Prompts and response payloads are logged and saved to third-party databases. | Zero Payload Retention by default: 0 bytes of conversation text stored on disk. |
Runaway Billing Spikes Recursive agent loops and surges | No central ceiling. Runaway loops can incur thousands of dollars overnight. | Hard monthly dollar spend limits trip circuit breakers before excess charges occur. |
Multi-Provider Overhead Deploying Claude, OpenAI, and Groq | Juggling disparate SDKs, unique headers, authentication keys, and dashboards. | One unified OpenAI-compatible endpoint for 147+ models. Switch models in seconds. |
Token Pricing Markup Per-token inference expense | Third-party marketplaces often add 15% to 30% margin on top of raw token prices. | 100% BYOK with 0% token markup: Pay providers directly at standard wholesale rates. |
