What is SolanaFM?
SolanaFM is a block explorer for Solana that shows transactions, network stats and tracked wallets. Its API documentation lists a free tier with 10 requests per second and 1 GB of bandwidth.
How SolanaFM works
SolanaFM indexes Solana and serves the same data to its explorer and to a public REST and WebSocket API at api.solana.fm.
Endpoints cover tagged accounts, account transactions and transfers, owned token accounts including NFTs and compressed NFTs, blocks, daily transaction fees, token info and supply, mint token accounts, and SNS domains with favorites and subdomains. A transfers CSV endpoint, /v0/accounts/{hash}/transfers/csv, takes action filters and a UTC start and end time.
Account endpoints return labels for known addresses, and a separate tagged token list returns the tokens SolanaFM has identified. Errors follow standard HTTP codes: 400 for a badly formatted parameter, 404 for a missing resource, 429 when you exceed the rate limit and 500 for a server fault. All calls must use HTTPS; plain HTTP requests fail.
How to start with SolanaFM
- Browse solana.fm without an account.
- For code, the API overview says the APIs are free of charge and gated by rate limiting, so you can call api.solana.fm endpoints over HTTPS directly.
- Heavier endpoints have their own caps: 10 requests per second for account transactions and transfers, 5 for token holders, supply and token accounts, and 1 for an address's token list and for CSV exports.
SolanaFM fees and limits
- The rate limits page lists a single plan: Free, $0, 10 requests per second, access to APIs and webhooks, and 1 GB of bandwidth, with extra bandwidth priced at $0.
No paid tier appears in the docs. SolanaFM only reads data, so the only other cost is the Solana network fee on transactions you send through your own wallet elsewhere.
Risks to know before using SolanaFM
- The API overview and rate limits pages were last updated on April 22, 2025, and the overview says newer API versions go first to users who opted into a beta, so endpoint paths can differ between users.
- The docs we read list no paid tier or uptime commitment, which makes SolanaFM a better fit for research scripts than for production systems that need guaranteed availability.
