Introducing: 402 Markets Explorer for X-Cashu & L402 pay-per-call API's. API information is stored on Nostr and follows OpenAPI 3.0 spec. More information below 👇

Since it's built on nostr you can publish your own API using your nostr identity and emoji react to other API's to help them build reputation.

I vibe coded this over the past two days, and instead of trying to perfect it, I’m just going to launch it and see how people use it and whether they find it useful.

The NUT-18 Cashu payment request for the Hello World test API doesn't work, at least not in Minibits. And Minibits supports NUT-18.

Lightning invoice doesn't work as well, missing channel connection.

Are you sure? What error do you get? Are you locking it to the pubkey and sending the correct amount? I tried both the testnut (free) and the minibits (paid)

I see the issue now. I think its because the payment request doesn't include `transport` but this is an issue with the nginx middleware I think.

Cashu NUT-18 requrst still doesn't work, gives me the error in the image.

As for Lightning, payment now works, but when entering the preimage, it doesn't work. Using Phoenix Wallet.

@Dhananjay Purohit Any ideas? I setup your nginx proxy but I suspect its because a `transport` is not included in the payment request.

Thanks for using it and pointing that out! You’re right — the transport field is missing, and I’ll fix that. I’m planning to add "t" as an empty array for now, since L402 currently uses an implicit transport method via X-Cashu headers. However, I’m open to discussing whether we should introduce explicit transport methods (like Nostr or HTTP POST) for receiving eCash, though that might add unnecessary complexity to the otherwise simple L402 protocol.

@stl1988 Its working fine with both minibits and phoenix wallet now. Thanks for testing it out.

Proudly built with ngx_l402 🛠️ and the power of Cashu 🥜, Lightning ⚡, and HTTP 402. The future of markets is here.
