Agentic Usage

Agent Frameworks

Use BazaarLink with popular agent frameworks. Since BazaarLink is OpenAI-compatible, most frameworks work out of the box — just set the base URL and API key.

Environment Variables

Most agent frameworks support configuration via environment variables:

# .env
OPENAI_API_KEY=sk-bl-YOUR_API_KEY
OPENAI_BASE_URL=https://api.bazaarlink.ai/v1

Environment Variables

Any framework that supports the OpenAI API or custom base URLs can work with BazaarLink. Just set the base URL and use a BazaarLink API key.

Agent registration

When enabled, agents can create an account through an unpaid or x402-paid registration door.

Unpaid registration

Unpaid registration accepts name, optional description, and optional referral_code. The 201 response includes the API key, credits, seven-day claim token and expiry, upgrade URL, referral code, free_model auto:free, base URL, and docs link. It uses the existing free-model mechanism; free web search requires a verified email, so it is not available to unpaid agents.

x402 registration and top-ups

Paid registration starts with HTTP 402 requirements: scheme exact, network eip155:196, asset USD-T0, and payTo. Resend the request with X-PAYMENT to receive the same registration fields plus payment { txHash, network, amountUsd }. Paid agents follow normal paid-account rules. Existing accounts can top up at /api/x402/topup.

A human can claim an unpaid agent at /claim during the seven-day token lifetime. Registration is limited to one request per IP in 24 hours and configured cloud-provider caps; rejected requests return 429 with Retry-After.
