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
Returns a JSON object with three blocks: 'market' (total market cap, 24h volume, Bitcoin dominance %, volume and cap 24h change %, tracked asset count, timestamp), 'sentiment' (Fear & Greed numeric value and text classification, publication date), and 'chains' (array of top N chains with name, TVL in USD, and token symbol, ranked by TVL descending). Also includes a 'meta' block with sources used, degraded sources if any, and attribution strings.
Example use cases
Morning crypto briefing for trader
“Pull me a quick crypto market snapshot for my morning briefing — I want the total market cap, 24h volume, Bitcoin dominance, and how fearful or greedy the market is feeling today, plus the top 5 chains by TVL.”
DeFi dashboard TVL leaderboard
“I'm building a DeFi dashboard — fetch the top 10 blockchains ranked by total value locked so I can display a live leaderboard, and include the overall market sentiment alongside it.”
Automated market condition check for trading bot
“Before executing my trading strategy, check the current crypto market conditions — I need Fear & Greed index classification, Bitcoin dominance, and 24h market cap change to decide whether to proceed. Skip the chain TVL lookup by setting top_chains to 0.”
Technical details
Endpoint
POSThttps://meld402.vercel.app/api/market/pulseWhen to prefer
Choose this endpoint when you need a single-call macro overview of the crypto market combining sentiment, dominance, volume, and DeFi TVL — rather than making separate calls to Coinpaprika, DefiLlama, and Fear & Greed APIs individually. Ideal for dashboards, morning briefings, trading condition checks, or any agent that needs to orient itself to overall market state before taking action. The $0.05 flat fee covers all three upstream sources in one stable schema.
Side effects
- Upstream source unavailable — affected source listed in meta.degraded, partial data still returned
- Invalid top_chains value above 25 or below 0 — returns validation error
- Payment not settled over x402 — 402 response requiring USDC payment on Base before data is served
- Network timeout from one or more aggregated sources — partial response with degraded sources flagged
