Overview

Messari’s API provided institutional-grade crypto asset data — metrics, market data, and news for thousands of assets. It was popular for analytics dashboards.

⚠️ Status (verified 2026-08): data.messari.io returns HTTP 404 on the documented endpoints (both /v1 and /v2 paths). Messari was acquired in 2024 and the free public API appears to have been discontinued. Do not build new projects on it — use the alternatives below.

What it used to provide

curl "https://data.messari.io/api/v1/assets/btc/metrics/market-data"

Alternatives

  • CoinGecko and Coinpaprika (both listed on this site) — free keyless crypto market data.
  • CoinMarketCap (listed) — key-based, authoritative.
