## 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 polymarket-wallet-activity-feed-cccef550
```

Example prompt: Pull the last 100 TRADE events from Polymarket's on-chain activity feed for wallet address 0x1234abcd...5678 so I can see what markets they've been buying and selling in.

## When to prefer this

Use this endpoint when you need a detailed, chronological record of a specific wallet's Polymarket on-chain actions — including trades, position management (splits/merges), redemptions, and rewards. Prefer it over market-level endpoints when the question is wallet-centric rather than market-centric. Ideal for portfolio analysis, wallet profiling, or auditing a trader's history on Polymarket.

## Known failure modes

- Missing required 'address' parameter returns a 400 or validation error
- Invalid or unrecognized wallet address returns empty results or 404
- Invalid 'type' enum value returns a 400 validation error
- Limit out of range (>500 or <1) returns a 400 error
- Wallet with no Polymarket activity returns an empty list
- Payment not included or insufficient USDC (x402) returns 402 Payment Required

## How this service works

A wallet's Polymarket on-chain activity feed: trades, merges, splits, redeems, conversions and rewards, newest first. Pass the wallet (proxy) address; optionally filter by type (TRADE/MERGE/SPLIT/REDEEM/REWARD/CONVERSION) and cap with limit. Each entry returns type, side, outcome, share size, price, USD value, timestamp, the market title/slug, conditionId, and tx hash. Read-only from Polymarket's Data API.

## Output

A list of on-chain activity entries for the wallet, each including: activity type (TRADE/MERGE/SPLIT/REDEEM/REWARD/CONVERSION), trade side (BUY/SELL), outcome, share size, price per share, USD value, timestamp, market title, market slug, conditionId, and transaction hash — ordered newest first.
