# Synapse API — Boba Network Token Metadata

> Synapse API — Boba Network 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 2026-09-13).

Retrieves on-chain token metadata (name, symbol, decimals, supply, etc.) for a given ERC-20 or similar contract address on the Boba Network blockchain.

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-boba-network-token-metadata-63ec9b2a -d '<json body>'
```

Example prompt: Can you look up the token metadata — name, symbol, and decimals — for the contract address 0x5008F837883EA9a07271a1b5eB0658404F5a9610 on Boba Network?

## When to prefer this

Use this endpoint when you specifically need token metadata from the Boba Network (an Ethereum Layer 2 using Optimistic Rollup technology). Prefer it over generic multi-chain APIs when you already know the token is on Boba, or when you need fast, pay-per-call access without a monthly subscription.

## Known failure modes

- Invalid or malformed contract address returns an error or empty response
- Contract address exists on a different chain (not Boba Network) yields no result
- Contract is not a token contract (e.g. a plain wallet or non-ERC-20 contract) may return empty or partial metadata
- Network downtime or RPC issues on Boba Network cause timeouts
- Payment failure via x402 blocks the request before execution

## 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 Boba Network contract address, typically including token name, symbol, number of decimals, total supply, and possibly other contract-level fields.
