Example use cases
DeFi TVL trend analysis
“Pull the historical TVL and market cap chart data for the Optimism chain from Blockscout so I can see how liquidity has trended over time.”

Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/stats/charts/marketWhen to prefer
Use this endpoint when you need historical market chart data (price, market cap, TVL) for a specific blockchain network by chain ID, particularly when working within the Blockscout ecosystem or needing cross-chain comparable data. Prefer this over CoinGecko or CoinMarketCap when you specifically need on-chain TVL data alongside market cap and price in a single call indexed by chain ID.
Side effects
- Invalid or unsupported chain_id returns an error or empty response
- Chain has no market data indexed by Blockscout — returns empty chart_data array
- Payment not processed — 402 response requiring x402 payment
- Rate limiting or network timeout on the Blockscout API
- Malformed chain_id path parameter causes 400 or 404 error
