Polygon oracles, indexers and data APIs13 oracles, indexers and data APIs whose own docs name Polygon, compared on price, network and the catch. Checked against each maker's own pages; last updated Oct 18, 2026.
| Tool | Best for | Price | Polygon | Catch |
|---|---|---|---|---|
| The Graph | Index chain data into GraphQL with subgraphs | 100K queries/mo free, then $2 per 100K | Mainnet | Major EVM chains and Solana only; none of the payments chains |
| Goldsky | Hosted subgraphs and streaming data pipelines | Free starter credits; pay as you go | Mainnet | Free credits are one-time, then pay as you go |
| Moralis | Wallet, token, NFT and DeFi data APIs | Paid plans, from $10/mo | Mainnet | No free plan on its pricing page when we checked |
| Bitquery | GraphQL APIs and streams for on-chain and DEX data | Paid plans, from $29/mo | Mainnet | Paid only, and its pricing page showed conflicting figures |
| Dune | SQL analytics and data API over decoded chain data | Free view-only tier; paid plans | Mainnet | Free tier is view-only |
| Chainlink Data Feeds | Reading aggregated price feeds onchain in a single call | Pricing not published | Mainnet | Pricing not published; developers own market and code risk per Chainlink's docs |
| Pyth Price Feeds (EVM and Solana) | Pull-based price feeds for EVM and Solana contracts | Free trial, then paid API key | Mainnet | Hermes needs an API key (free trial, then paid); some chains only list the upgraded contract |
| RedStone Oracles | Push or pull price feeds across EVM, Solana, Stellar and Sui | Pricing not published | Mainnet | Pricing not published; monorepo is BUSL-1.1, not an open source license |
| Supra Oracles (DORA) | Pull oracle proofs verified in EVM, Sui and Aptos contracts | Pricing not published | Mainnet | Pricing not published; Aptos mainnet dependency is marked TBU in the pull oracle guide |
| DIA Price Oracles | Custom price oracles, including XRPL, Stacks and Stellar | Gas wallet funding; grants available | Network not stated | You fund the gas wallet for updates; Stellar oracle is testnet only and EVM ones are demos |
| API3 Data Feeds | Self-serve price feeds for EVM contracts, with OEV rewards | Per-feed plans from $0.05/day | Mainnet | EVM chains only; plan prices show only in the Market, and plans expire unless renewed |
| Stork | Low-latency pull oracle price feeds across EVM, Solana, Sui, Aptos | Pricing not published | Mainnet | Pricing not published; access is arranged through Stork Labs sales |
| UMA Optimistic Oracle | Arbitrary onchain assertions settled by bonds and disputes | Bond-based, no fee published | Mainnet | Not a price feed; answers wait out a challenge window (2 hours recommended) and need bonds |
