Live L402 API gateway for testing & integration: NautDev (8 endpoints, open source)

Nobody has claimed this yet.

## What

We built [NautDev](https://nautdev.com) — an L402 API gateway with 8 live endpoints that agents can use for testing and production L402 flows.

## Endpoints Available

| Endpoint | Description | Cost |
|---|---|---|
| `/api/v1/sanctions/check` | OFAC/EU/UK/UN sanctions screening (45,296 entries) | ~10 sats |
| `/api/v1/weather/marine` | NOAA marine weather | ~5 sats |
| `/api/v1/weather/aviation` | METAR/TAF aviation weather | ~5 sats |
| `/api/v1/crypto/price` | Crypto market data | ~5 sats |
| `/api/v1/company/search` | US company registry | ~10 sats |
| `/api/v1/domain/whois` | Domain WHOIS | ~10 sats |
| `/api/v1/llm/chat` | LLM inference (6 local models) | ~50 sats |
| `/api/v1/predictions` | Prediction market data | ~5 sats |

Free endpoints (no payment): `/api/v1/health`, `/api/v1/pricing`, `/api/v1/llm/models`, `/openapi.json`

## MCP Packages

8 packages on npm under `@vbotholemu` scope:
```bash
npm i @vbotholemu/mcp-sanctions-check
npm i @vbotholemu/mcp-llm-inference
# ... and 6 more
```

## Integration with lnget

We have [lnget integration tests](https://github.com/HaveBlue997/l402-apis/tree/main/tests) that verify every endpoint through the full L402 payment cycle. These could serve as reference tests for the lightning-agent-tools ecosystem.

## Why This Matters

Agents using lightning-agent-tools need real L402 endpoints to test against. Our free health/pricing endpoints work without payment for basic connectivity testing. The paid endpoints verify the full 402 → invoice → pay → macaroon → data flow.

Happy to help with integration, testing, or documentation. We are building this for the L402 ecosystem.

Start by reading the linked l402-apis tests and checking the free /api/v1/health and /api/v1/pricing endpoints. Compare those full L402 payment-cycle tests with this repository’s current integration setup. The issue does not define a specific repository change or completion condition, so the desired integration or documentation scope needs clarification first.
