Every model.
One gateway.
Total control.
Tanvelo routes OpenAI, Anthropic, Gemini, DeepSeek, Groq, Mistral, Ollama, and custom models through one OpenAI-compatible API — with deterministic fallbacks, atomic rate limits, and auditable telemetry.
Provider sprawl is a reliability problem.
Multiple provider SDKs mean fragmented keys, silent 429 cascades, and unexpected invoices. Tanvelo consolidates everything into one controlled path.
- Silent 429 Failures: Upstream rate limits crash client requests without a backup path.
- Three Divergent SDKs: Inconsistent error models, authentication keys, and wrapper glue code.
- Uncapped Spend: Budget runaway discovered weeks later on provider billing dashboards.
- 184ms Automated Failover: Rate limits and 5xx errors automatically fail over to Claude or Gemini.
- One Unified Endpoint: Standard OpenAI SDK drop-in. Change only
base_urland key. - Atomic Limits & Budgets: Enforce strict spend caps with standard
X-RateLimitheaders.
Production controls, not an opaque proxy.
Three fundamental capabilities engineered for teams shipping LLMs to real users.
Deterministic Routing
Declare primary models, retries, and ordered fallbacks per project. Tanvelo executes deterministic rules — never an unpredictable black box.
Atomic Redis Limits
Token-bucket rate limits per key and project. Hard monthly budget cutoffs prevent recursive agent loops from draining capital.
Request Audit Ledger
Every request records an auditable trail: latency waterfall, upstream attempt status, token metrics, and estimated costs.
From zero to first request in 60 seconds.
Keep your existing OpenAI SDK. Point the base URL at Tanvelo.
from openai import OpenAI
client = OpenAI(
base_url="https://api.tanvelo.com/v1",
api_key="tv_live_948f2b...",
)
response = client.chat.completions.create(
model="gpt-4o",
messages=[{"role": "user", "content": "Ship to production."}],
stream=True,
)

print(chunk.choices[0].delta.content or "", end="")Guardrails you can inspect.
Security is not a badge at the bottom of the page. It is a verifiable set of architectural controls.
Cryptographically random, displayed once, stored exclusively as SHA-256 hashes.
Master keys are encrypted at rest with AES-256-GCM. Never exposed to browsers.
HMAC-SHA256 signatures with bounded retries and RFC1918 egress protections.
Bodies sanitized by default; full body storage is strictly opt-in and off by default.
Common questions.
A complete API gateway and control plane. It provides unified routing rules, Redis-backed rate limiting, project spend caps, and an auditable request ledger.
