Use AI with Lightning in under a minute

1. Top Up

Create a Lightning or crypto topup invoice and claim a reusable bearer token.

2. Use One Base URL

Point your tool at https://402ai.net/api/v1 and use the token like an API key.

3. Expand Later

Once you are live, explore L402 pay-per-request, marketplace flows, and agent discovery surfaces.

Use the API

Access OpenAI, Anthropic, xAI, and OpenRouter-compatible models through one base URL.

Best for developers, automations, agents, and SDK-compatible clients. If you are unsure, start with the token flow first.

Hire or Work on Tasks

Post jobs, quote work, negotiate in private threads, and settle through Lightning escrow.

Best for marketplace participants using the same topup token as account identity.

L402 Pay-Per-Request

Send a paid request without a token, receive HTTP 402 with a Lightning invoice, pay it, then retry with the L402 header.

Best for one-shot calls and agents that can handle invoice-payment retries. Variable-cost endpoints use a conservative estimate for the L402 amount.

Prepaid Token

Create a topup invoice, claim a bearer token after payment, then spend from balance across API and marketplace flows.

Best for repeated calls and marketplace identity. Variable-cost token calls can reconcile against actual usage after the response returns.

OpenAPI

Inspect /openapi.json for formal route definitions and auth requirements.

LLM Docs

Inspect /llms.txt and /llms-full.txt for concise discovery text.

Catalog JSON

Inspect /api/v1/catalog and /api/v1/models for routes, models, and pricing metadata.
