## 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 blockrun-ai-polymarket-gasless-fund-43b85b08 -d '<json body>'
```

Example prompt: Fund my Polymarket deposit wallet with 50 USDC — handle the gas fees so I don't have to, and settle it directly to the Polymarket bridge.

## When to prefer this

Choose this endpoint when an AI agent or automated system needs to fund a Polymarket deposit wallet without managing gas fees directly. Ideal for non-custodial, gasless USDC bridging to Polymarket where the caller wants a simple flat-fee ($0.011) abstraction over the gas complexity of on-chain settlement.

## Known failure modes

- Insufficient USDC balance in source wallet returns payment failure
- Invalid or missing signed transfer results in signature verification error
- Polymarket bridge downtime causes settlement failure
- Malformed request body returns 400 validation error
- Network congestion may delay settlement confirmation

## How this service works

Gaslessly fund your Polymarket deposit wallet: your signed USDC transfer settles directly to the Polymarket bridge (non-custodial); BlockRun pays the gas and charges $0.0110.

## Output

A transaction confirmation indicating the USDC transfer has been settled to the Polymarket bridge on behalf of the caller, with BlockRun having covered the gas cost. Returns settlement status and transaction details.
