WatchData review
A focused RPC and blockchain data service with a free tier and five supported chains.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
WatchData provides cloud-based blockchain APIs and node infrastructure for developers building wallets, payment services, crypto exchanges, DeFi analytics, and on-chain metrics. Its APIs cover Bitcoin, Ethereum, Tron, Binance Smart Chain, and Polygon, with raw and structured on-chain data, full archive access, cryptocurrency price data, and dedicated nodes. It is aimed at teams that want node and data access through an API rather than maintaining their own blockchain node infrastructure.
The free plan includes 100,000,000 watch units per month and 5 apps. According to the vendor's pricing page, Start Up costs $49 per month or $500 per year and includes 200,000,000 watch units per month and 10 apps. Business costs $99 monthly or $1010 annually, with 450,000,000 watch units and 15 apps. Production costs $299 monthly or $3050 annually, with 600,000,000 watch units and 20 apps. Enterprise is listed as a custom plan. The paid tiers raise usage and app limits; teams should compare their expected demand with those caps before choosing a plan.
The product's depth is in combining node access with indexed data: APIs expose balances, transactions, blocks, token transfers, and logs, while powered APIs return structured block, transaction, and event-log information. Ethereum access includes JSON-RPC methods such as eth_call, eth_getLogs, and eth_sendRawTransaction, and dedicated nodes also provide JSON-RPC access. Email, community, and documentation are listed support channels, with 24/7 support stated. WatchData is a fit for teams whose needs center on these five networks and API-based archive access; projects requiring broader chain coverage should consider an alternative.
