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.

Uniswap Rate Limits is the machine-readable rate-limit profile for Uniswap on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 2 rate-limit definitions, measuring queries_per_month and varies.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Blockchain, DeFi, Subgraph, and Rate Limiting.

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.
