## 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 overwatch-desk-prediction-market-trade-idea-submission-96a9bdbc -d '<json body>'
```

Example prompt: Submit my Polymarket trade idea to the Overwatch Desk: I think YES on 'Will the Fed cut rates in September?' at an estimate of 0.65, max price 0.68, on the BUY side — here's my evidence doc at https://mygdrive.com/fed-analysis, and pay any profits to my Base address 0xAbCd1234...5678.

## When to prefer this

Use this endpoint when you want to monetize a prediction-market edge without executing the trade yourself — specifically when you have a well-reasoned probability estimate on a Kalshi or Polymarket market and want a funded desk to execute it in exchange for 30% of realized profit. Prefer this over direct trading APIs when you lack capital, want asymmetric upside, or want your estimate locked before seeing live market prices to avoid anchoring bias.

## Known failure modes

- Missing required fields (venue, market, side, estimate, max_price, payout_address) returns a 4xx validation error
- Invalid venue name (not Kalshi or Polymarket) causes rejection
- Malformed Base payout address results in submission failure
- Evidence URL unreachable or backtest data invalid may lead to rejection with reason
- Payment of $0.01 USDC not received causes 402 Payment Required error
- Duplicate or already-priced ideas may be rejected by the desk with explanation

## How this service works

Submit a prediction-market trade idea to the Overwatch Desk (Kalshi or Polymarket). Your estimate is locked before any price is shown. Accepted ideas are traded with the desk's own money; you get a negotiable share (15-50%) of realised profit to your Base address. Every submission gets a decision and reason: GET /desk/{id}. Body: venue, market, side, estimate, max_price, payout_address, evidence_url or backtest.

## Output

Returns a JSON object with a submission ID, a status of 'received', and a status_url path (e.g. /desk/{id}) where the agent can poll for the desk's decision, acceptance or rejection reason, and eventual profit-share outcome.
