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 response containing an AI-generated natural-language answer about current Bitcoin fees, mempool conditions, and timing recommendations, along with an 'ok' boolean status and a 'source' field identifying the service.
Example use cases
Optimal fee timing for Bitcoin wallet
“I want to send some Bitcoin from my wallet — can you check the mempool and tell me if fees are low enough to send now, or if I should wait a few hours?”
Cost estimate before on-chain payment
“Before I pay this Bitcoin invoice, can you tell me roughly how much extra I'll spend on fees right now and whether the network is congested?”
Automated DCA bot fee gating
“My recurring Bitcoin purchase is about to execute — check current mempool conditions and tell me whether fees are reasonable or if the bot should pause and retry later.”
Technical details
Endpoint
POSThttps://bitcoinsapi.com/api/v1/ai/chatWhen to prefer
Choose this endpoint when you need a conversational, AI-interpreted answer about Bitcoin fees and mempool state rather than raw data — ideal for agents that need actionable advice phrased in plain language, or when integrating Bitcoin fee intelligence into a chat-based workflow without parsing raw mempool JSON yourself.
Side effects
- Payment not provided or invalid x402 payment header returns 402 status
- Malformed or empty query body returns error
- Bitcoin network data temporarily unavailable leads to stale or degraded response
- Rate limiting if payment is not processed correctly
