Retrieve historical wallet token balances across 150+ blockchains via Allium's onchain data API.
What it does
This MPP endpoint from Allium returns historical wallet balance data — letting agents query how a wallet's token holdings changed over time across 150+ supported chains (EVM, Solana, Bitcoin, and more). Allium is the data infrastructure provider behind Phantom, Uniswap, and Coinbase, indexing billions of on-chain records.
The 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.
Because 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.
Capabilities

- —Building portfolio performance dashboards with historical balance snapshots
- —Auditing wallet activity across multiple blockchains
- —Feeding historical balance data into AI agents for on-chain analysis
- —Tracking DeFi position changes over time
Fit
Best for
- —AI agents needing programmatic access to historical on-chain wallet data
- —Developers building multi-chain portfolio trackers
- —Analysts auditing wallet balance changes across 150+ chains

- —Users needing a free, fully documented public API (pricing and docs are sparse)
Quick start
# Likely requires POST — exact schema unknown. Install Allium skills:
npx skills add https://github.com/allium-labs/skills --yes
# Or call directly (hypothetical, verify with docs.allium.so):
curl -X POST https://agents.allium.so/api/v1/developer/wallet/balances/history \
-H 'Content-Type: application/json' \
-d '{"address": "0x...", "chain": "ethereum"}'Endpoint
Quality
The endpoint returned 405 on HEAD/GET so no 402 MPP challenge was captured, meaning liveness is unconfirmed via the expected protocol. No OpenAPI schema, no documentation (docs page 404), no pricing, and no request/response examples were found. The listing is largely inferred from the provider's landing page and the endpoint URL path.
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.
