Web3 Provider Watch — 2026-09-22

To claim. Nansen Meridian still offers 2× API credits on purchases through September 27 and lists 1,000 free API credits through its Points Hub. Check the Points Hub while signed in; the public page cannot establish account-specific eligibility. To enter the buildathon, create an API key, make 1,000 calls during September 14–27, post a demo recording on X tagging @nansen_ai, then submit the X post and a public GitHub repository by September 27 at 23:59 UTC. Geomi now publishes its standing monthly usage credits clearly: $10 automatically per organization, or $100 with a payment method. Usage above the allowance is metered, so check the Usage tab before adding a card.

New coverage. Ankr added Somnia mainnet to Advanced API Token, NFT and Query methods on September 21; its Somnia JSON-RPC endpoint already existed. Use somnia_mainnet as the blockchain value. Somnia is now a named network in this tracker (additive schema v0.3). The same notice corrects two testnet names: eth_holesky is not served by Advanced API, and optimism_testnet must be optimism_sepolia. Ankr says prices and limits did not change.

Act by date. Moralis removes Moonbeam, Moonriver and Lisk from its Data API, Streams, RPC Nodes and Datashare on September 25; export needed history and remove those chain IDs from streams beforehand. Nansen closes September 27. Alchemy's legacy NFT endpoints sunset September 30, while Sui's JSON-RPC archival fallback ends around the end of September—the Sui docs do not specify an exact day. QuickNode raises Solana gRPC metering and retires port 10000 on October 1; move to port 443 with x-token auth. Arbitrum Open House submissions close October 4. The September 21 Alchemy wallet-default date and September 22 Avalanche Helicon activation time have passed, but static official pages do not independently confirm either rollout completed; their dated reminders were removed, not relabeled as verified live.

Changes and risk. Chainstack's current Business price is $499/month or $416/month on annual billing; the older contradictory $349/$290 figure was removed, with no evidence of a new price rise. The Graph Market's landing page now says 54 networks rather than 71; its free 7M blocks and 5 GiB egress are unchanged, and the reason for the count difference is unknown. Triton publishes regional Shred Streaming rates: $900–$1,500/month in its currently offered locations, with 15-minute options; the $450/month tier is listed for other cities that require inquiry. At the time of this run, Blockdaemon and QuickNode reported a Cosmos-wide chain halt; check their live status before relying on Cosmos data.

Gaps. This catch-up checked the 30 oldest provider records after a two-day scheduling gap. dRPC Solana, mempool.space, Syndica, TonAPI paid tiers, Transpose and Unmarshal could not be fully read; Arkham's published API rates and TronGrid's exact keyed quotas also remain unverified. No past-day run was invented.
