Why Nexo

A simpler way to ship AI features.

One balance, many models

Top up a single Nexo account and spend across every supported model. No per-provider contracts, no separate dashboards.

Prepaid, by design

You control the ceiling. Redeem a top-up code whenever you need more credit, spend it down, redeem again.

Drop-in API

Standard chat-completions format over HTTP. Point your existing client at Nexo, swap in your key, ship.

How it works

Your first call in under two minutes.

01

Create an account

Email + password. That's it.

02

Redeem a top-up code

Paste the code on the Billing page. The credit lands on your balance immediately.

03

Call the API

Point any standard client at nexoapi.com/v1/chat/completions with your key.

example.sh
curl https://nexoapi.com/v1/chat/completions \
  -H "Authorization: Bearer sk-••••••••" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4o-mini",
    "messages": [{"role": "user", "content": "Hello"}]
  }'
