It tracks token and native coin balance changes at configurable intervals, enabling analysis of holding patterns, transaction activity, and portfolio evolution.\n\nThe endpoint accepts POST requests with a JSON body specifying the address (or entity name), chain, date range, and optional filters (token symbol, token address, value in USD, spam token hiding). It supports pagination (up to 1000 records per page) and custom sort ordering by block timestamp, value in USD, or token symbol. Supported chains include Ethereum, Solana, Base, Arbitrum, Bitcoin, Polygon, BNB, and many others. The response returns timestamped balance records with token address, chain, token amount, USD value, and token symbol.\n\nPricing is $0.01 per call via the x402 protocol, or 10 credits (free tier) / 1 credit (pro tier) when using a Nansen API key. Rate limits are enforced per-second and per-minute, reported via response headers. The endpoint returns 402 for unauthenticated callers as part of the x402 payment challenge flow.","tags":["blockchain","smart-money","wallet","tokens","defi","analytics","profiler","dex","pnl","onchain","prediction-market"],"capabilities":["historical-balance-tracking","wallet-profiling","multi-chain-support","entity-name-resolution","token-filtering","pagination","custom-sorting","spam-token-filtering","x402-payment"],"categories":["blockchain-analytics","wallet-profiling"],"synonyms":["wallet balance history","address historical holdings","portfolio evolution","token balance over time","wallet profiler","blockchain balance snapshots","address balance timeline","Nansen profiler"],"warnings":["No human-readable documentation pages were accessible (docs, pricing pages returned 404)","Response schema fields are inferred from the OpenAPI component ProfilerHistoricalBalance; no live 200 response was captured"],"endpointUrl":"https://api.nansen.ai/api/v1/profiler/address/historical-balances","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"api.nansen.ai","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.880","qualityRationale":"Full OpenAPI 3.1 schema with detailed request/response models, clear pricing ($0.01 via x402), and a live 402 challenge captured.
