Top NFT APIs in 2025: Reservoir vs. SimpleHash vs. NFT Price Floor

What’s the best NFT API in 2025?

The NFT data space has undergone major shifts over the past few years. What began as a fragmented, experimental ecosystem has become an infrastructure battleground, where precision, speed, and multi-chain coverage are everything. Whether you're building an NFT marketplace, a wallet feature, or a price analytics tool, your backend is only as good as the data it pulls in.

Until recently, two names dominated the NFT API race: Reservoir and SimpleHash. They were the go-to tools for developers looking to plug into real-time metadata, ownership history, floor prices, and more. But 2025 is not 2023. In the past year, tectonic changes in the NFT data landscape have completely reshaped the options available to developers and analysts.

This article breaks down:

What makes a great NFT API

The recent fates of SimpleHash and Reservoir

Why NFT Price Floor is emerging as a compelling alternative

Let's dive into what’s happened, and what’s next.

What Makes a Good API for NFTs in 2025?

The ideal NFT API needs to solve a few key challenges:

Cross-chain coverage – Ethereum is still king, but Solana, Bitcoin Ordinals, and emerging L2s like Base have made multi-chain support essential.

Up-to-date metadata and floor prices – Collections are dynamic, not static. The best APIs reflect price changes, metadata refreshes, and ownership updates in real time.

Customizable endpoints – Developers need flexibility. Whether you're building a marketplace, a portfolio tracker, or an AI model, static endpoints don't cut it.

Reliability – With fewer marketplaces and more sophisticated aggregators, reliable uptime and SLA-backed performance are non-negotiable.

Licensing and longevity – In the fast-moving NFT space, you don’t want to depend on an API that might shut down next month—or change its terms unpredictably.

With these factors in mind, let’s review the current state of the top NFT APIs.

SimpleHash: Cross-chain Powerhouse Turned Phantom Memory

SimpleHash emerged in the early 2020s as one of the most comprehensive NFT data APIs available. Its strength? True cross-chain support. While most of its competitors focused on Ethereum and Polygon, SimpleHash stood out by covering Solana, Bitcoin Ordinals, and newer ecosystems like Tezos and Stacks. For wallets and apps looking for unified NFT data across chains, it was the holy grail.

Why it was great:

✅ Multi-chain support (EVM, Solana, Bitcoin, Tezos)

✅ Real-time metadata updates

✅ Easy-to-integrate, RESTful endpoints

✅ Strong wallet focus—great for asset overviews

But that wide focus may have been its Achilles' heel.

In early 2025, SimpleHash was acquired by Phantom, the most widely used Solana wallet. It made sense on paper—Phantom needed native indexing and wallet-level NFT visualization. But with the acquisition came a quiet sunsetting of the public-facing SimpleHash API.

Where it stands now:

❌ As of Q2 2025, SimpleHash has ceased open API operations

❌ No developer-facing roadmap

✅ Still powers some Phantom-native functionality

⚠️ Not an option for public or third-party NFT apps anymore

Bottom line: If you were relying on SimpleHash for Bitcoin or Solana NFT data, you’ll need to find an alternative.

Reservoir: EVM Deep-Dive That’s Being Decommissioned

If you were building anything on Ethereum, Polygon, or Arbitrum in the last few years, Reservoir was probably part of your stack.

Known for its developer-first approach, Reservoir offered robust NFT APIs and SDKs focused on:

Floor price indexing

Market listings

Collection metadata

Ownership verification

And most importantly—it was modular. Developers could build their own marketplace frontends, wallets, and analytics tools with Reservoir’s open SDKs and Relay aggregation engine.

Why it was a developer favorite:

✅ Real-time data from OpenSea, Blur, LooksRare, and more

✅ Support for EVM chains (ETH, Polygon, Arbitrum, Base)

✅ Permissionless listing and bidding support

✅ Actively maintained SDK and docs

However, by mid-2025, things began to change.

Reservoir’s team announced they would be winding down their core NFT API and SDK services by October 2025 to focus entirely on their Relay protocol, a liquidity layer that aggregates NFT orders across marketplaces.

This means developers will no longer be able to rely on Reservoir's open APIs for NFT data. The shift is strategic, but it leaves a major gap in the ecosystem—especially for projects building dashboards, trackers, or custom analytics.

Where it stands now:

⚠️ Still active, but winding down open API support

❌ No long-term roadmap for public API maintenance

✅ Relay protocol will continue for aggregation use-cases

❌ SDK users must migrate by Q4 2025

Bottom line: If you’re using Reservoir today, you’ll need to migrate soon or risk building on a deprecated service.

NFT Price Floor: The OG enters the API market

While others scale back, NFT Price Floor has quietly emerged as the most stable, community-trusted alternative for NFT data.

If you've been in the NFT space since 2021, you probably know NFTPriceFloor.com as one of the earliest tools to track floor prices, market caps, and collection performance. It offered a “CoinGecko for NFTs” dashboard before most marketplaces had public APIs at all.

Fast forward to 2025, and NFT Price Floor has built its own [proprietary API infrastructure]( https://nft-api.nftpricefloor. com/), informed by four years of real-world floor price tracking, market volatility, and collection behavior.

Why it's worth your attention now:

✅ First-mover advantage in NFT floor price tracking (since 2021)

✅ Proprietary dataset, not dependent on external aggregators

✅ Dedicated API for floor prices, rankings, collection stats, and more

✅ Enterprise-grade SLA for teams building serious tools

✅ Proven track record—they’ve been doing this longer than most

While SimpleHash leaned into multi-chain and Reservoir into liquidity aggregation, NFT Price Floor has stayed laser-focused on what it does best: reliable NFT data.

And with both former giants scaling back, it's now in a prime position to lead.

Where it stands now:

✅ Fully operational and expanding

✅ Used by wallet providers, analytics dashboards, and NFT funds

✅ Offers historical data, API integrations, and developer support

✅ Active product roadmap, with integrations planned for L2s and Solana

Bottom line: If you're looking for a serious, stable NFT data provider in 2025, NFT Price Floor is the rising contender filling the gap left by others.

The Verdict

In previous years, the answer to “Which NFT API should I use?” would have been a toss-up between Reservoir for EVM or SimpleHash for cross-chain.

But in 2025, neither option is viable for long-term projects.

With both services shutting down their public APIs, the NFT data landscape has entered a new phase—and NFT Price Floor is rising to meet the challenge with a focused, stable, and battle-tested approach to NFT market data.

If you're building in the NFT space today, the real question isn’t “what’s next?” It’s “who’s still here, and doing it right?”

NFT Price Floor may be the last one standing—but it’s also standing stronger than ever.
