# Synapse API — Gnosis Token Transfers

> Synapse API — Gnosis Token Transfers 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 2026-09-14).

Retrieves token transfer history for a given wallet address on the Gnosis blockchain network, with optional filtering by block range, contract addresses, and pagination.

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-gnosis-token-transfers-a479ae98 -d '<json body>'
```

Example prompt: Pull all token transfers for Gnosis wallet 0xAbC123...789 from block 30000000 to 30500000, sorted descending, limit to 100 results, and only include transfers from contract 0xTokenContract...456.

## When to prefer this

Use this endpoint when you specifically need token transfer history on the Gnosis (xDAI) network. Prefer it over generic blockchain explorers when you need programmatic, paginated, filterable access to transfer events for a wallet or set of token contracts on Gnosis. Not suitable for Ethereum mainnet or other EVM chains — check sibling endpoints for those.

## Known failure modes

- Invalid owner address format returns validation error
- Unknown or malformed contractAddresses entries may return empty results
- Invalid block range (fromBlock > toBlock) may return error or empty response
- Invalid pageKey causes pagination failure
- Rate limits or payment failures return 402 or 429 errors
- Network downtime for Gnosis RPC returns 503
