Look up token metadata by chain and contract address via Allium's onchain data API.
What it does
This Allium endpoint lets agents look up token information by specifying a blockchain chain identifier and a contract address. It is part of Allium's AgentHub platform, which provides enterprise-grade blockchain data across 150+ chains (EVM, Solana, Bitcoin, and more). Allium's infrastructure powers products at Phantom, Uniswap, and Coinbase.
The endpoint is listed as an MPP (machine-payable protocol) resource. However, during probing it returned HTTP 405 (Method Not Allowed) on both HEAD and GET requests, which suggests it may require a POST method or specific path parameters (chain and address) to be supplied in the URL. The Allium landing page states that AgentHub supports x402 payments in USDC on Base, with traditional API key authentication as an alternative. No OpenAPI schema, pricing details, or dedicated documentation were found for this specific endpoint.
Because the probe did not capture a 402 payment challenge or a successful response, the exact request format, response schema, and per-call pricing remain unconfirmed. Users should consult Allium's official documentation at docs.allium.so or the GitHub skills repository for integration details.
Capabilities
Use cases
- —Resolving token metadata (name, symbol, decimals) from a contract address on a specific chain
- —Enriching wallet portfolio views with token details
- —Validating token contract addresses before executing trades
- —Building cross-chain token databases for analytics dashboards
Fit
Best for
- —AI agents that need programmatic onchain token lookups
- —Multi-chain portfolio trackers requiring token metadata
- —DeFi applications resolving token contracts across 150+ chains
Not for
- —Real-time token price feeds (separate Allium endpoint exists for prices)
- —Non-blockchain use cases
- —Users needing free unlimited access without payment or API key
Quick start
# Allium AgentHub skill install (Claude Code / OpenClaw)
npx skills add https://github.com/allium-labs/skills --yes
# Then query token by chain and address:
# POST https://agents.allium.so/api/v1/developer/tokens/chain-address
# (exact request body/params TBD — see Allium docs)Endpoint
Quality
The probe did not return a 402 challenge or any successful response (405 on HEAD and GET), so liveness is unconfirmed. No OpenAPI schema, no endpoint-specific documentation, and no pricing details were captured. The listing is largely inferred from the Allium landing page and the endpoint URL pattern.
Warnings
- —Endpoint returned 405 on both HEAD and GET — may require POST or path parameters; liveness via MPP protocol unconfirmed.
- —No OpenAPI or JSON schema available for request/response formats.
- —No per-call pricing information captured; Allium landing page mentions USDC on Base via x402 but no specific amounts.
- —Allium docs page (agents.allium.so/docs) returned 404 at crawl time.
