Uniswap Rate Limits

Uniswap does not publish a centralized API rate-limit policy because the protocol is on-chain. Subgraph queries flow through The Graph Network and inherit that platform's billing-driven throttling - usage above the 100K monthly free tier is charged rather than throttled. On-chain interactions are governed by Ethereum and L2 block-space limits, not application-layer rate limits. For production reliability, Uniswap recommends self-hosting subgraphs.

Provided by The Graph Network for any subgraph, including Uniswap subgraphs. Beyond the free tier, additional queries are billed at $2 per 100K rather than throttled.

No application-layer rate limit; throughput is constrained by network gas and block size.

Policies

Self-Host for Production
Uniswap docs explicitly recommend deploying and managing your own subgraph using official repositories for production reliability rather than relying solely on shared public endpoints.
Pay-As-You-Go on The Graph
Excess subgraph query volume is billed by The Graph rather than hard-throttled, assuming an active card or GRT balance is configured in The Graph Studio.
Decentralized Network
Hosted subgraphs are deprecated; queries must go through The Graph's decentralized network using a Studio-issued API key.
