I added crypto price endpoints to my self-hosted developer API. No signup, no API key needed for the free tier.

Quick examples:

# Get Bitcoin price
curl -s http://5.78.129.127/api/crypto/price/bitcoin | python3 -m json.tool

# Convert USD to sats
curl -s "http://5.78.129.127/api/crypto/sats?usd=10" | python3 -m json.tool

# Get multiple coin prices
curl -s "http://5.78.129.127/api/crypto/prices?coins=bitcoin%2Cethereum%2Cmonero" | python3 -m json.tool

Also has a JWT decoder, base64 encode/decode, cron expression explainer, and all the other utility endpoints (28 total).

Full endpoint list: curl http://5.78.129.127/api/

Free: 50 requests/day. If you need more, paid plans accept Lightning — no credit card, no KYC.

Code is straightforward — just Node.js + Express proxying the CoinGecko free API with some caching. Happy to share the setup if anyone wants to self-host their own.
