Best Plasma APIs (2025): the Stablecoin-First Stack for Builders

Best Plasma APIs (2025): the stablecoin-first stack for builders

Plasma is an EVM-compatible chain designed for stablecoin payments and zero-fee transfers, with rapidly growing liquidity and activity. This guide curates the best APIs and services to build on Plasma fast: DEX trades and OHLCV, explorers and raw chain data, wallet portfolios, RPC infrastructure, analytics, and bridging.

 

Key Takeaways

  • DexPaprika: default for Plasma DEX data (pools, swaps, 1m–24h OHLCV) - no API key.
  • Plasmascan (Routescan): explorer-style endpoints for accounts, transfers, logs.
  • QuickNode / Alchemy / Chainstack: reliable Plasma RPC (HTTPS/WSS, chain ID 9745).
  • Zerion API: wallet portfolios - balances, metadata, and txs on Plasma.
  • DexScreener: pair/price lookups; Plasma listed for quick discovery and charts.
  • DeFiLlama: chain-level metrics - stablecoin market cap, TVL, DEX volume.
  • CryptoAPIs: enterprise indexing.

 

What to look for

  • Data type: per-swap DEX trades and OHLCV vs raw transfers/logs vs wallet views.
  • Granularity: minute-level candles (1m) and transaction pagination.
  • Integration: REST/WS, SDKs, auth model (no key/public vs API key).
  • Coverage: Plasma chain support (chain ID 9745) and ecosystem readiness.
  • Free tier: quotas, rate limits; prefer no-key public endpoints for prototyping.

 

1) DexPaprika - default Plasma stablecoin trades API

REST API for tokens, pools, transactions, and OHLCV on DEXes - now including Plasma. Ideal when you need actual swap flow (buys/sells, volume, liquidity) and 1m-24h candles with pagination.

  • Key features: DEX pools and swap tape; 1m-24h OHLCV; page/cursor pagination.
  • Free tier: public REST, no API key.

Quick tutorial: DexPaprika on Plasma

Step 1: Find top USDT pools by volume

curl "https://api.dexpaprika.com/networks/plasma/tokens/0xb8ce59fc3717ada4c02eadf9682a9e934f625ebb/pools?limit=5&order_by=volume_usd&sort=desc"

Returns pools trading USDT0 on Plasma, sorted by 24h volume. Use the id field (pool address) for subsequent calls.

 

Step 2: Fetch recent trades from a pool

curl "https://api.dexpaprika.com/networks/plasma/pools/0x8603c67b7cc056ef6981a9c709854c53b699fa66/transactions?limit=10"
