How this service works
Pay-per-call tools for AI agents: web page text extraction and summaries, screenshots, image generation, speech-to-text, image description, domain and email-auth intelligence, and live Base token and wallet lookups. No account or API key; pay per request in USDC on Base via x402.
Output
A JSON object containing fee estimates in sat/vB for multiple confirmation targets (nextBlock, halfHour, hour, economy, minimum), the current Bitcoin block height, mempool statistics (vsize in vBytes, total fees in BTC, transaction count), and typical payment cost in sats for hour and next-block confirmation targets.
Example use cases
Optimize Bitcoin transaction fee before sending
“Before I send this Bitcoin payment, what fee rate should I use to get it confirmed in the next block vs. within an hour? What's the mempool looking like right now?”
Monitor Bitcoin network congestion for trading bot
“Check the current Bitcoin mempool size and fee rates — I need to know if the network is congested and what the economy fee is right now.”
Estimate Bitcoin withdrawal cost for exchange
“What would a typical Bitcoin payment cost in sats right now at the next-block fee rate, and what's the current sat/vB rate I should use?”
Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/btc-fees?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs real-time Bitcoin fee rate data without setting up an account or API key, and is willing to pay $0.002 USDC per call via x402 on Base. Prefer this over self-hosted mempool APIs when simplicity and pay-per-use economics matter. Good for agents that need occasional fee lookups rather than high-frequency polling.
Side effects
- Payment not received or invalid USDC payment on Base — returns HTTP 402 with payment instructions
- Upstream Bitcoin node/mempool data source unavailable — may return 5xx error or stale data
- Network timeout from Cloudflare Worker — returns 5xx
- No input parameters required so malformed requests are unlikely, but unexpected query params are ignored
