How this service works
Know when to send Bitcoin and when to wait. Satoshi API gives apps and AI agents live fee recommendations, mempool context, and cost estimates. Free, open source.
Output
A JSON object containing the original txid, the provider name ('satoshi-api'), and a plain-English explanation of the transaction's fee level and expected confirmation behavior based on current mempool conditions.
Example use cases
Diagnose a stuck Bitcoin payment
“My Bitcoin payment has been pending for hours — txid is 9f3e2c1b0a7d... — can you explain why it might be stuck and whether the fee was high enough to get confirmed?”
Understand a received transaction
“Someone just sent me Bitcoin and gave me txid 4d8a1f2e3c9b... — can you break down what's happening with it in plain English, including whether it'll confirm quickly?”
Audit fee quality for a sent transaction
“I just sent a Bitcoin transaction with txid 7e1c4f9d2a3b... — was the fee I paid reasonable given current mempool conditions, and when do you think it'll confirm?”
