All-in on Optimized Metadata: NFTs & ERC20s in Insight
We’ve just completed a full rollout of metadata performance upgrades across all NFT-related API routes — and started extending the same treatment to ERC20s.
What’s New?
✅ Optimized Metadata Across All NFT Routes
Every API call involving NFT metadata now performs a single, efficient data read per request — even for multichain queries. Whether you're pulling transfers, balances, or metadata directly, things just got a whole lot faster.
🚀 Performance Gains: NFT Metadata Latency Drops by 10x+
We’ve slashed the latency for NFT metadata queries — and the numbers speak for themselves. For example, data for GET /v1/nfts/:contract_address
| Metric | Before | After | 🔻 Improvement |
|---|---|---|---|
| p50 | 103 ms | 5.9 ms | ~17× faster |
| p75 | 152 ms | 13.4 ms | ~11× faster |
| p90 | 243 ms | 54.8 ms | ~4.4× faster |
| p95 | 327 ms | 99.3 ms | ~3.3× faster |
| p99 | 464 ms | 192.1 ms | ~2.4× faster |
| p99.9 | 555 ms | 242.3 ms | ~2.3× faster |
| Max | 756 ms | 290.2 ms | ~2.6× faster |
GET /v1/nftsandGET /v1/nfts/transfersalso saw solid improvements in the ~1.1× to 2.9× range, with reduced tail latencies and smoother performance across the board.- Not just faster — more consistent, with reduced tail latencies and fewer spikes in production.
- These performance gains are now live for all metadata queries hitting the NFT endpoints.
🧱 ERC20 Metadata Storage Begins
We’ve started persisting ERC20 metadata as well, laying the foundation for more efficient token balance queries with rich metadata. Stay tuned — optimized joined queries are on the way.
🔄 Unified NFT Balances Endpoint
We’ve consolidated NFT balance queries under a single route:/v1/nfts/balance/{ownerAddress}
This new endpoint works across ERC721 and ERC1155 standards, supports multichain queries out of the box, and is the one we recommend going forward.
Heads up: the old ERC721/ERC1155-specific balance endpoints are still live, but are now officially deprecated.
This makes it easier than ever to query, display, and work with NFTs and tokens at scale — with less overhead and more consistency.
