Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability phantom-api-sei-token-metadata-93badabe -d '<json body>'
```

Example prompt: Can you look up the token metadata — name, symbol, and decimals — for the SEI contract at address 0xAbC123... using on-chain data?

## When to prefer this

Use this endpoint when you specifically need token metadata (name, symbol, decimals) for a contract deployed on the SEI blockchain. Prefer this over generic blockchain explorers when you need programmatic, pay-per-call, low-latency access without API key registration. Best suited for agents performing automated token lookups, portfolio enrichment, or pre-trade verification on SEI.

## Known failure modes

- Invalid or malformed contract address returns an error response
- Contract address not deployed on SEI network returns not-found or empty metadata
- Non-token contract address (e.g. a plain smart contract) may return incomplete or missing metadata fields
- Network congestion or RPC unavailability may cause timeout or 5xx errors
- Payment failure via x402 protocol results in 402 response blocking the request

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns on-chain token metadata for the specified SEI contract, typically including token name, symbol, decimal places, and other contract-level properties stored in the token's metadata fields.
