# Synapse API — Celo Token Metadata Lookup

> Synapse API — Celo Token Metadata Lookup 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 2026-09-15).

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

## 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-celo-token-metadata-lookup-601c7f45 -d '<json body>'
```

Example prompt: Can you look up the token name, symbol, and decimals for the Celo contract at address 0x765DE816845861e75A25fCA122bb6898B8B1282a?

## When to prefer this

Use this endpoint when you specifically need token metadata from the Celo blockchain by contract address. Prefer it over generic multi-chain tools when the target network is confirmed to be Celo and you need fast, pay-per-call access without API key setup.

## Known failure modes

- Invalid or malformed contract address returns an error or empty response
- Contract address exists but is not a standard ERC-20/token contract, so metadata fields may be missing
- Contract not deployed on Celo network returns not-found or null result
- Network congestion or RPC issues may cause timeouts
- Payment failure via x402 prevents the call from executing

## How this service works

## Output

Returns on-chain token metadata for the given Celo contract address, typically including the token name, symbol, and decimal precision as recorded in the smart contract.
