Technical details
Endpoint
POSThttps://stablecrypto.dev/api/alchemy/portfolio/nftsWhen to prefer
Use this endpoint when you need to enumerate all NFT holdings for one or more wallet addresses on a specific EVM-compatible network. Prefer this over the NFT collections endpoint when you want individual token-level balance data rather than collection-level aggregates. It is backed by Alchemy's indexed data making it reliable for mainnet and L2 queries.
Side effects
- Invalid or unsupported network slug returns an error
- Malformed wallet addresses cause validation failures
- Missing required fields (network or addresses) returns a 400-style error
- Empty addresses array may return empty results
- Network congestion or Alchemy upstream issues may cause timeouts
- Payment not included or insufficient causes x402 payment required error
