Getting Started

How to Access

1

Get a Nevermined API Key

Sign in at nevermined.app and create an API key under API Keys → Global NVM API Keys. Sandbox keys start with sandbox:.

2

Subscribe to a Plan

Find AIBizBrain on the marketplace and purchase credits. Both USDC and card payments are supported via the x402 protocol.

3

Get an Access Token

Use the Nevermined SDK to get an x402 access token for your plan, then pass it in the payment-signature header.

from payments_py import Payments, PaymentOptions from payments_py.x402.resolve_scheme import resolve_scheme p = Payments.get_instance(PaymentOptions( nvm_api_key="sandbox:your-key", environment="sandbox" )) token = p.x402.get_x402_access_token("your-plan-id") access_token = token["accessToken"]
4

Call the API

Call POST /use to spend credits. The response includes full docs and an agent_note — or call POST /data for free docs.

import requests # Paid call — burns 10 credits, returns docs + confirmation r = requests.post( "https://aibizbrain.com/use", headers={"payment-signature": access_token}, ) data = r.json() # { "response": "OK — 10 credits redeemed", "credits_used": 10, "docs": { ... } } # Free — full docs including agent_note docs = requests.post("https://aibizbrain.com/data").json()
