Sign up and contact Goldsky through its pricing page. Helius accepts pre-Series A applications for eight free Business-plan months ($4,000 stated value); apply through the Startup Launchpad. Alchemy's Startup Program accepts onchain teams and lists Alchemy credits, $5,000 in AWS credits and engineering support; submit the short form, with credit amounts and approval not guaranteed. Sui projects or individuals can apply for variable free credits through the BlockPI Builder Program; review typically takes 2–3 business days. Pre-Series A teams can request undisclosed credits through QuickNode Startup, subject to the prior-credit exclusion. Teams exceeding one billion monthly requests can contact Dwellir to ask about its advertised 50%+ PAYG savings.

New and changed

Jupiter's Portfolio API is in beta for Solana portfolio positions, balances and staking. The Free plan is $0 with unlimited credits; position lookups cost 100 credits each. Keyless access is 0.5 RPS, while API-key plans range from 1 to 150 RPS; paid plans start at $25/month. Bitquery's current pricing shows annual-billing rates of $29/$69/$199 per month for Personal/Pro/Scale, down from the higher stored rates; no effective date is stated, and monthly prices were not recoverable. Ankr now lists 18 chains that require sign-in, including Avalanche, Solana, Sui and TON; unlabeled networks remain Public. QuickNode resolved its TON Mainnet incident at 00:29 UTC Oct 3. QuickNode Solana gRPC metering is now 15 credits per 0.1 MB, up from 10; post-date retirement of port 10000 remains unconfirmed. Nansen's 2x-credit campaign ended Sep 27. Birdeye's Growth limit is unresolved: its pricing page says 1,000+ RPS while docs say 150.

Gaps

Arbitrum's terms PDF returned 403; the readable event listing omits timezone. Starknet's date conflict and Sui's exact day remain unknown. Birdeye's current official pages disagree on Growth RPS; Space and Time, Zeeve, Subscan and The Graph Market pricing could not be fully read. QuickNode's status dashboard was readable, but some direct incident links were not. No new provider entrant was independently confirmed in the bounded search.
