Unified API

Different chains. One URL.

One endpoint format, one key, one schema. EVM and non-EVM from a single integration.

  • One subdomain per chain

    Each chain answers on its own host — <chain>.therpc.io/<key>. Switch chains by switching the subdomain; the key and the call shape stay the same.

  • EVM + non-EVM, one schema

    Ethereum, Arbitrum, Base, Polygon, Solana, Bitcoin, TON, TRON, Sui — JSON-RPC 2.0 for EVM and Solana, REST wrappers for TRON and TON.

  • One-click Add to MetaMask

    Every EVM chain ships a button with a prefilled RPC URL and Chain ID.

Frequently asked

Short answers. The docs go deeper.

A Compute Unit (CU) is our single billing unit across every chain. Each call is billed in CU — light reads cost the least, heavier methods like traces, large ranges and archive cost more. One unit, every chain, no per-chain surcharge. On Pay-as-you-go, 1M CU = $0.39.

Crypto-native — top up in USDC and other stablecoins. No card required.

Each plan exposes a per-key RPS ceiling you control from the dashboard. The Pay-as-you-go plan lets you raise the limit on demand.

Enterprise plans include a contractual SLA with credits. Free and Pay-as-you-go tiers run on best-effort multi-region capacity with a public status page.
