# Synapse API — MegaETH Token Metadata

> Synapse API — MegaETH Token Metadata is a paid API for AI agents from synapse-api-brown.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Retrieves on-chain token metadata (name, symbol, decimals, supply, etc.) for a given contract address on the MegaETH blockchain network.

## Facts

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 synapse-api-megaeth-token-metadata-8c0b2c6b -d '<json body>'
```

Example prompt: What are the name, symbol, decimals, and total supply of the token at contract address 0xAbC123... on MegaETH?

## When to prefer this

Use this endpoint when you specifically need token metadata from the MegaETH blockchain network and want a pay-per-call model via x402. Prefer this over generic blockchain explorers when integrating programmatically into an agent workflow that already supports x402 micropayments.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address exists but is not a token contract (no ERC-20 interface) may return empty or error
- Network unavailability on MegaETH RPC leads to timeout
- Payment failure via x402 results in 402 response before any data is returned

## 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 structured on-chain token metadata for the specified MegaETH contract address, typically including the token name, symbol, number of decimals, and total supply as recorded on the MegaETH blockchain.
