How this service works
14 paid data endpoints for autonomous agents and developers. Covers crypto intelligence (token, chain, Solana, gas), markets (FX, market pulse), location (weather), and research (news, brief). Each route aggregates multiple public sources into one stable schema with a single USDC payment over x402 on Base.
Output
A JSON object with four sub-sections: fees (speed-tiered sat/vbyte rates, 24h median and average fees in sat and USD, suggested rate), chain (block height, hashrate, difficulty, next retarget time, node count, 24h tx count, next difficulty estimate), market (BTC price in USD, dominance %), and mempool (size in bytes, pending tx count, tx/s). Also includes metadata: timestamp, contributing sources, and degraded-source warnings.
Example use cases
Optimal fee for urgent BTC send
“What's the fastest fee rate I should use right now to get a Bitcoin transaction confirmed in the next block? Include the fastest, half-hour, and economy sat/vbyte tiers.”
Bitcoin mining difficulty tracker
“What is Bitcoin's current mining difficulty, estimated hashrate, and when is the next difficulty retarget expected?”
Mempool congestion check before batching
“How backed up is the Bitcoin mempool right now? I need the number of pending transactions, mempool size in bytes, and transactions per second before I decide whether to batch my payouts.”
Technical details
Endpoint
POSThttps://meld402.vercel.app/api/btc/networkWhen to prefer
Choose this endpoint when you need a single, stable, multi-source Bitcoin network snapshot covering fees, chain health, mempool, and market data in one call. It is especially useful for agents that need to make fee recommendations, monitor network congestion, or provide BTC market context without stitching together multiple upstream APIs. Prefer over raw Blockchair or mempool.space calls when you want aggregated fee tiers and resilience to individual source downtime.
Side effects
- mempool.space rate-limited or blocked — fee tiers may be missing; set include_fee_tiers:false to fall back to Blockchair's single suggested rate
- Blockchair API unavailable — chain and market data may be absent; response includes degraded[] list identifying affected sources
- Payment rejected — 402 response if USDC payment over x402 on Base fails or is insufficient
- Malformed request body — 400 error if JSON is invalid
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| include_fee_tiers | boolean | Query mempool.space for per-speed fee tiers. Set false to skip it and rely on Blockchair's single suggested rate, which is faster and never blocked. |
