About

Codex is an API for enriched blockchain and prediction market data. For tokens, it covers real-time pricing, charts, holders, balances, and aggregated analytics for 80M+ tokens and 700M+ wallets across 80+ networks (EVM chains and Solana), with sub-second freshness, historical USD pricing, and WebSocket and webhook subscriptions. Codex also provides prediction market data across Polymarket and Kalshi through a single schema. This includes events, markets, traders, holdings, live order books, and trade feeds, along with time-windowed stats and ranking signals (volume, liquidity, open interest, trade count, and unique traders) at 5m through 1w windows that the venue APIs do not expose natively. Codex is a GraphQL API that most teams query directly, with an optional TypeScript SDK. There is also an MCP server for reading the documentation. Codex offers a free tier (10,000 requests/month), usage-based Growth pricing, and Enterprise plans. Developers use it to build trading platforms.

Pros & Cons from Real Users

Pros

  • Absolutely flawless I like the speed, accuracy, chain coverage and prices are reasonable and i am using it since more than a year.
  • NOWNodes provides reliable blockchain infrastructure with a wide range of supported networks. The API is straightforward, the documentation is clear, and the integration process is smooth. Their support team is responsive, professional, and always helpful when resolving technical issues.
  • The team is very responsive. We asked about the ARC network and it was live shortly after. Setup was straightforward, and we get answers on a shared channel the same day.
  • We've been using NOWNodes for over three years at TeleSwap, a decentralized Bitcoin bridge that connects Bitcoin with other blockchains. We use their RPC services across multiple networks, including Bitcoin, Polygon, and BNB Smart Chain, and our experience has been great. The biggest thing for us is reliability. I honestly can't remember the last time we had an outage or any downtime with their service. When you're running a cross-chain bridge, having reliable RPC infrastructure is really important, and NOWNodes has been rock solid for us. It's one of those services that just works, and you don't have to worry about it.
  • NOWNodes gives the multi-chain cryptowallet I work in a reliable access to a broad range of blockchain networks without requiring our team to maintain every node internally. This is particularly valuable for a multi-chain wallet like ours, where infrastructure requirements can vary significantly from one network to another. I also appreciate the stability of the service and the responsiveness of their technical support when an issue requires investigation.

Cons

  • I didn't find any till date, like they are integrating more chains i would like if they integrate base testnet
  • Nothing significant to complain about. Overall, the experience has been great, and the team is continuously improving the service.
  • Nothing major so far. It has been stable since we started, and the few questions we had were sorted out quickly.
  • Honestly, nothing major comes to mind. We've been happy with the service and haven't had any significant issues.
  • Personally, I would appreciate even more proactive and detailed communication around network-specific incidents, planned maintenance, upgrades, and degraded performance. Earlier visibility into what is affected, the expected impact, and whether any action is required on our side would make troubleshooting across multiple networks even more efficient.
