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 a `data` field with a `token` sub-object (price, ATH/ATL, market cap, volume, supply, description, GitHub and social metrics) and an `on_chain` sub-object (contract address, balance, verification status, transaction counts), plus a `meta` field listing data sources, degraded sources, and attribution strings with timestamps.
Example use cases
DeFi portfolio token due diligence
“Give me the full token intelligence report for USDC on Base — market cap, circulating supply, 24h volume, on-chain contract address, and any GitHub or social stats you can find.”
Crypto trading signal research
“What's the current price, 24h price change, and all-time high for Arbitrum's ARB token on the Arbitrum chain? I want everything aggregated from multiple sources.”
Smart contract token verification
“Look up token details for the contract address 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 on Ethereum — I need its name, symbol, on-chain transfer count, and whether the contract is verified.”
Technical details
Endpoint
POSThttps://meld402.vercel.app/api/token/intelWhen to prefer
Choose this endpoint when you need a single, unified view of a crypto token combining both market data and on-chain data in one call, without stitching together multiple APIs yourself. It is especially useful for agents that need a quick, stable schema across many chains (eth, base, polygon, arb, opt, etc.) and want social/developer activity metrics alongside price data. Prefer it over raw CoinGecko or Etherscan calls when you want normalized, multi-source output with built-in attribution and degradation tracking.
Side effects
- Token not found for the given query string — returns empty or error response
- Chain identifier not recognized — may return data for default chain or error
- Upstream source (CoinGecko or block explorer) degraded — response may be partial with affected sources listed in meta.degraded
- Payment not received or insufficient — x402 payment required error before data is returned
- Contract address on wrong chain — on_chain data may be empty or mismatched
