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 containing: global market stats (total market cap, 24h volume, BTC/ETH dominance, active exchanges and cryptocurrencies, volume and market cap change percentages), a list of top N assets (price, market cap, 24h and 7d price changes), category performance data (market cap, volume, 24h change per category), DEX volumes by chain (top DEX, volume, 24h change), stablecoin supply data (supply and market cap per stablecoin), and DeFi TVL by chain (1d and 7d change). Also includes metadata with data sources, timestamp, and attribution.
Example use cases
Morning crypto market briefing
“Pull the full market pulse for me — top 20 assets, category breakdown, stablecoin supplies, and DEX volumes — so I can see how crypto is doing before the trading day starts.”
DeFi dashboard data refresh
“Fetch a market snapshot with all 50 top assets, DEX volumes per chain, and DeFi TVL so I can update my portfolio dashboard.”
Crypto market health check for report
“Get me a comprehensive crypto market overview including global market cap, BTC dominance, volume changes, and the top-performing categories right now — I need the numbers for a weekly summary.”
Technical details
Endpoint
POSThttps://meld402.vercel.app/api/market/pulse-proWhen to prefer
Use this endpoint when you need a broad, multi-dimensional crypto market snapshot in a single API call rather than stitching together CoinGecko and DefiLlama separately. Ideal for dashboard refreshes, daily briefings, or market health checks where you want global stats, top assets, category performance, DEX volumes, stablecoin supply, and TVL all normalized into one consistent schema. Prefer this over direct CoinGecko or DefiLlama APIs when you want a single payment, single request, and unified data model.
Side effects
- Upstream CoinGecko or DefiLlama outage — degraded field in meta lists affected sources with partial data still returned
- top_n exceeds 50 — request rejected with validation error
- Payment not processed or USDC balance insufficient — 402 response requiring x402 payment
- Network timeout from aggregation layer — 5xx error
