Get your live #bitcoin exchange rates on Sintra. Price and fee history available. https://sintra.fi

2024-11-21 19:43:00 UTC

For anyone who isn’t glued to the screen waiting for 100k to land there’s a new endpoint on Sintra for pro users. You can now retrieve #bitcoin transaction fee history. 🚀

2024-11-20 10:18:03 UTC

https://sintra.fi is a great place to watch Bitcoin hit new all time highs in real time. #bitcoin #lightning #api

Sintra now displays the live #btcusd price in your browser tab. #bitcoin

2024-11-14 21:48:22 UTC

Pro plan is available again now. Sorry about that. #bitcoin

2024-07-29 13:14:03 UTC

Closing in on the 70k mark. Let it rip 💪 #bitcoin

2024-07-20 15:51:54 UTC

#bitcoin price is coiling. Explosive move incoming. 📈

2024-06-06 11:47:26 UTC

The calm before the storm 📈 #bitcoin

2024-05-15 08:23:14 UTC

Currently building #webhooks for Sintra so your apps can be alerted when a #bitcoin goes to the moon or more likely transaction fees hit the roof. 📈
Reminder: you can currently get transaction fees using an API call or via a websocket connection. https://sintra.fi?ref=nostr

2024-05-13 10:16:39 UTC

#bitcoin transaction fees are now available on Sintra to both Free and Pro plan users with support for websockets too. Coming soon, there’ll also be a fee history endpoint to Pro users (just need to give it some time so there’s enough data). https://sintra.fi

2024-05-12 16:17:10 UTC

Transaction fees down to 12sats/vB. Good time to get that #bitcoin off exchanges and get those utxos sorted 😉

If anyone else is interested in running an instance of phoenixd send a DM 👍

2024-05-07 19:01:19 UTC

Replaced Lightning node with an instance of #phoneixd and using it to accept Pro plan purchases on Sintra. It’s nice not to have to worry about liquidity and channels and I could see this approach becoming a little more popular.

2024-05-05 08:02:01 UTC

480 sats/vB. And on a Sunday! 😩 #mempool #bitcoin.

2024-04-29 17:13:48 UTC

Switching from a Lightning Node to an instance of #phoenixd. Fits the bill better as no channel management or worrying about capacity. Should be in place soon but in the meantime the Pro plan is unavailable. #bitcoin #lightning #phoenixd

2024-04-26 18:24:52 UTC

So is it a good or bad time to run #phoenixd at the moment?

2024-04-17 06:29:44 UTC

Building something cool for #Bitcoin and need to show live prices? Take a moment to check out Sintra https://sintra.fi

Feel free to try Sintra for the price. Feedback always appreciated 👍

Ok, well Sintra provides live prices and price history among other things but something like mempool could be useful for you if you want to listen for transactions etc

What kind of Bitcoin data?

2024-04-04 15:40:45 UTC

So where can lightning be used to pay for stuff in #zug Switzerland? Going tomorrow. ⚡️

2024-03-28 14:47:07 UTC

Better get started building a webhook delivery platform 😟 #bitcoin #btc

2024-03-27 22:18:29 UTC

So who’s got a little project on the go and needs live Bitcoin prices via an API? No signing up, no authentication and no credit cards. DM if you need some help integrating 👍

Grayscale just needs to do one 😏

For those new to holding Bitcoin, the price doesn’t just go up. Enjoy the drops, let others sell to Blackrock and in time you will be left holding the premier digital asset that can’t be debased or confiscated. #btc #bitcoin

2024-03-17 11:31:33 UTC

Added websocket access to the Sintra free plan. The homepage now uses this to show continually updating prices which has been great for watching prices go down recently 😂 https://sintra.fi

Hey 👋. Only just realised #introductions hashtag was a thing. Been using Nostr for a few weeks now so let me firstly say hi. As a passionate “Bitcoiner” I wanted to try and contribute something to the community so I’ve been busy building out a Bitcoin Price API https://sintra.fi
Feel free to check out the site and I welcome feedback. See you around.✌️

2024-03-15 10:39:44 UTC

Just finishing up the websocket server for the Free plan on Sintra. It’s as simple as connecting to the ws endpoint to start receiving price data. No auth or API keys required. 🎉 #btc #bitcoin #api #dev

Do you have the details of the Yorkshire walk?

The price history endpoint now supports a date parameter so you can specify a cut off point for your historical prices. https://sintra.fi

UPDATE. I’ve revamped the plans on Sintra so now there’s just a free plan and a pro plan (coming soon). You don’t even need an API key to start using the free plan so you can get live prices and price history as easy as this👇 https://sintra.fi

Any devs out there working on a project that needs to convert btc to a fiat currency? Sintra is looking for some help testing our API. Feel free to DM 💪

2024-03-06 07:57:29 UTC

Expecting to revisit all time high territory soon against the usd. Then it’s price discovery mode which should be fun #btc

2024-03-05 09:13:56 UTC

Whilst the price of Bitcoin is approaching all-time highs, did you know you can get more than just current live prices from Sintra. You can also retrieve historical prices and price actions. DM to register your interest in joining our beta testing.

Proud to say that anyone wanting to use the #sintra API can do so without giving an email address, personal information or credit card information. And there's no tracking or annoying cookie consent popups either. #btc #bitcoin #lightning
