2026 became the year free blockchain APIs largely disappeared. Blockscout moved all traffic to a paid Pro API on July 1. Dune's simulation APIs shut down on August 1. Blocknative switched its APIs off in June. GetBlock retired flat per-request billing, making heavy calls more expensive. Pyth's Hermes endpoint, which thousands of teams used without credentials, now requires an API key.

The shift marks a turning point for Web3 infrastructure. For years, developers could prototype applications on free tiers, gradually moving to paid plans as their projects scaled. That model is largely gone. What remains are a handful of genuinely generous free offerings, a much larger number of decorative free tiers that stop at 100 credits, and a growing number of providers hiding their entry prices behind sales calls.

The practical impact is significant. A developer building a portfolio tracker, tax tool, or wallet application typically needs four separate services: a price API, a wallet balance API, a DeFi position decoder, and something for analytics. That meant four vendors, four billing relationships, and four different data schemas to reconcile. Now, with free tiers shrinking, the cost of stitching together a prototype has jumped considerably.

What Happened to Free Tier Generosity?

The consolidation reflects a broader maturation in Web3 infrastructure. Early blockchain APIs were built as loss leaders, designed to attract developers and build network effects. As the market stabilized and infrastructure providers faced pressure to become profitable, free tiers became unsustainable. Companies that once offered unlimited free access now meter it in credits, restrict it to specific features, or eliminate it entirely.

The remaining free offerings vary wildly in what they actually provide. Some free plans are genuine products that can sustain a working prototype for months. Others are demos designed to get developers in the door before hitting a paywall. The difference between the two is now the difference between shipping a product and re-architecting in month three.

Which Providers Still Offer Meaningful Free Access?

A few infrastructure providers have maintained genuinely useful free tiers, though they come with different tradeoffs. Blockscout, the open-source blockchain explorer, offers the most generous free tier on the market: 100,000 credits per day at 5 requests per second across 120+ chains. Since most endpoints cost 20 credits, that translates to roughly 5,000 calls per day, every day, on every supported chain.

Codex, a token indexing service, provides 10,000 requests per month after a one-time $1 verification charge. The service indexes tokens the moment they hit the chain, returning live prices, OHLCV data (open, high, low, close, volume), holder analytics, and wallet balances through a single GraphQL schema across 80+ networks.

CoinStats offers 20,000 credits per month at 2 requests per second, with no feature gates between free and paid tiers. The same infrastructure serves over a million users of the CoinStats app, making it production-tested rather than a data product built for resale. A single API key returns market data for 100,000+ coins, wallet balances across 120+ blockchains, DeFi positions across 10,000+ protocols, and portfolio analytics.

How Are Developers Adapting to the Shift?

With free tiers shrinking, developers are pursuing three main strategies. The first is consolidation: choosing a single provider with the broadest feature set rather than stitching together multiple vendors. This reduces engineering complexity and billing overhead, even if it means paying for features not immediately needed.

The second strategy is self-hosting. Blockscout, for example, is open source, allowing teams to run their own instance for a specific chain rather than relying on a hosted service. This trades operational overhead for cost control and independence from a third-party provider's pricing decisions.

The third approach is building custom infrastructure. Goldsky, for instance, lets teams define a subgraph and handles hosting and scaling. Pinax operates a streaming layer that most teams don't realize they need until polling stops scaling, offering block-level data across 46 chains and WebSocket subscriptions across 30+ chains on a single connection.

How to Choose a Blockchain API Provider in 2026

• Evaluate breadth first: A provider that returns prices, balances, transaction history, and protocol positions from one credential saves more engineering time than one that returns any single category faster, reducing the number of vendors and billing relationships needed.
• Test free tier honesty: Distinguish between a free plan that stops at 100 credits (a demo) and one that covers a working prototype for months (a product decision), then commit based on realistic usage patterns.
• Verify published pricing: Any provider whose entry price is hidden behind a sales call should rank below one with transparent pricing you can read off a page, avoiding surprise costs during scaling.
• Check coverage and speed requirements: Determine whether you need direct node access, decoded transaction history, live price feeds, or specific blockchain support, then match that to the provider's actual capabilities rather than marketing claims.
• Consider operational overhead: Weigh the cost of integrating multiple APIs against the cost of a single provider's paid plan, including the engineering time spent reconciling different schemas and managing multiple credentials.

The shift away from free blockchain APIs reflects a maturing market. Infrastructure providers are no longer competing primarily on free tier generosity; they're competing on breadth, speed, reliability, and the operational overhead they save developers. For teams still in the prototype phase, the remaining free tiers are worth knowing precisely, because the gap between a generous one and a decorative one is now the difference between shipping and re-architecting.

The era of unlimited free access to blockchain data is effectively over. What remains is a smaller set of providers offering genuinely useful free tiers, a much larger number offering minimal free access, and a growing number of teams building their own infrastructure to avoid vendor lock-in and unpredictable pricing changes.
