Allium is the data infrastructure provider behind Phantom, Uniswap, and Coinbase, indexing billions of on-chain records.\n\nThe endpoint is part of Allium's AgentHub, which packages enterprise-grade blockchain data for AI agents. AgentHub supports both x402 machine-to-machine payments (USDC on Base) and traditional API key authentication. However, during probing this specific endpoint returned HTTP 405 on both HEAD and GET, suggesting it likely requires a POST method or specific request parameters that were not tested. No OpenAPI schema, pricing details, or request/response examples were found in the crawl.\n\nBecause no 402 challenge was captured and documentation pages returned 404, the exact request format, required parameters (e.g., wallet address, chain, date range), response schema, and per-call pricing remain unknown. Users should consult Allium's main documentation at docs.allium.so or the GitHub skills repository for integration details.","tags":["blockchain","prices","tokens","wallet","balances","transactions","pnl","sql","explorer","solana","base","defi"],"capabilities":["historical-wallet-balances","multi-chain-support","evm-chains","solana","bitcoin","token-balance-tracking","onchain-data","x402-payment","api-key-auth"],"categories":["crypto","blockchain-data","finance"],"synonyms":["wallet balance history","historical token balances","onchain wallet tracker","blockchain portfolio history","wallet holdings over time","crypto balance API","multi-chain wallet data"],"warnings":["Endpoint returned HTTP 405 on HEAD and GET — likely requires POST but this was not probed; liveness via MPP challenge is unconfirmed.","No OpenAPI or schema documentation was found; request parameters and response format are unknown.","Allium docs page (agents.allium.so/docs) returned 404 at crawl time.","Pricing per request is not documented in any crawled material.","No example request or response could be captured or inferred with confidence."],"endpointUrl":"https://agents.allium.so/api/v1/developer/wallet/balances/history","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"agents.allium.so","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.250","qualityRationale":"The endpoint returned 405 on HEAD/GET so no 402 MPP challenge was captured, meaning liveness is unconfirmed via the expected protocol.
