## 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 synapse-api-pharos-token-metadata-82719153 -d '<json body>'
```

Example prompt: Can you pull the token metadata — name, symbol, and decimals — for the contract address 0xAbC123...def456 on the Pharos network?

## When to prefer this

Use this endpoint when you need to resolve token metadata specifically on the Pharos blockchain network and are comfortable with pay-per-call pricing via x402. Prefer this over generic multi-chain explorers when targeting Pharos specifically, or when you need a lightweight programmatic lookup without a full blockchain node.

## Known failure modes

- Invalid or malformed contract address returns an error response
- Contract address does not exist on Pharos network returns not-found or empty result
- Non-token contract address (e.g. NFT or generic contract) may return unexpected or partial metadata
- Network congestion or RPC unavailability may cause timeouts
- Payment failure via x402 prevents the call from being processed

## How this service works

High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.

## Output

Returns on-chain token metadata for the specified contract address on the Pharos network, typically including the token name, symbol, decimal precision, and potentially other contract-level attributes stored in the token's metadata.
