How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

Returns current Bitcoin mempool fee estimates across different confirmation speed tiers (e.g. fastest, half-hour, hour), expressed in satoshis per vByte, reflecting real-time mempool congestion.

Example use cases

Pre-transaction fee check

“Before I send this Bitcoin payment, what fee rate should I use in sat/vByte to get it confirmed within the next block?”

Mempool congestion monitoring

“Is the Bitcoin mempool congested right now? What are the current fast, medium, and economy fee estimates?”

Cost-conscious BTC transfer

“I want to send Bitcoin but I'm not in a rush — what's the cheapest sat/vByte fee I can set and still realistically get confirmed within an hour?”

When to prefer

Use this endpoint when an AI agent needs real-time Bitcoin transaction fee recommendations without requiring API key registration. Ideal for pay-per-call workflows via x402/USDC where the agent autonomously decides the fee tier for a pending BTC transaction. Prefer over manual mempool.space scraping or heavier blockchain node integrations.

Side effects

Mempool data source unavailable — returns error or stale data
Network timeout if Bitcoin node connection is slow
Invalid schema parameter returns 400 or empty response
Mempool data may lag real-time by a few minutes during high congestion
