Everything you need to ship AI to production

One integration gives you the whole frontier, with the controls a production workload needs.

One API for every model

Switch labs by changing one string. Same OpenAI-compatible request, same SDK, same balance.

client.chat.completions.create({

model:"vichar-opus-5.5"

messages,

})

Failover built in

If a route errors or times out, the request is retried on another route for the same model.

Route Atimeout
Route B200 OK

Retried automatically · failed attempt not billed

Spend limits per key

Cap each key with a monthly budget and an expiry, so a runaway job can never drain your balance.

InputOutput

One request. Any model.

Your app sends one request. Vichar routes it to the lab that serves the model you asked for, with the same request and response shape every time.

For developers

Change two lines.
Keep your SDK.

Streaming, tool calling and structured outputs work the same way across every lab. The Anthropic Messages format works too.

Your whole AI spend, in one dashboard

Requests, tokens, latency and cost for every key, project, model and provider, updated in real time.

Cost per key and model

Find the expensive workload in seconds.

Keys with budgets

Spend caps, expiry and one-click revoke.

Errors and reliability

Error rates and retries per provider.

Start in minutes

Step 1

Create an API key

Sign up, add credits from $20, and create a key with its own spend limit and expiry.

Step 2

Change your base URL

Point any OpenAI-compatible SDK at api.vichar.io/v1. The rest of your code stays the same.

Step 3

Ship on any model

Pick models per request, and watch tokens, latency and cost per key in the dashboard.

Frontier models, ready to call

Live per-token pricing from the catalogue.

Browse all 0 models

    Input / output per 1M tokens

    Simple, honest pricing

    Listed model rates, a flat fee when you add credits, and nothing for requests that fail.

    0%

    Token markup

    Every request is billed at the model's published input and output rate.

    5%

    Top-up fee

    A flat platform fee when you add credits. A $20 top-up costs $21.

    $0

    For failed requests

    Requests that fail before a provider answers never deduct credits.

    See pricing and cost calculator

    Private and secure by default

    We keep the metadata needed to bill you, nothing more.

    Prompts are not stored

    By default we keep only billing metadata: tokens, cost, latency and provider.

    Keys hashed at rest

    Keys are stored as one-way SHA-256 hashes and shown in full only once.

    Encrypted in transit

    HTTPS only, TLS 1.2+, between your app, Vichar and every provider.

    Questions, answered

    • Yes. Point your client at https://api.vichar.io/v1 and use a Vichar API key. Your existing code keeps working.
