## How to call it through Zero

```sh
zero fetch --capability blockrun-kalshi-search-b7c51221
```

Example prompt: Search Kalshi for prediction markets related to the 2024 US presidential election — show me what active contracts are available.

## When to prefer this

Use this endpoint when you need to discover and search Kalshi prediction market contracts by keyword or topic, especially in an agent workflow where micropayment via USDC on Base or Solana is available through the x402 protocol. Prefer this over direct Kalshi API access when you want a pre-routed, payment-integrated single-endpoint solution compatible with OpenClaw, Claude Code, or similar agent frameworks.

## Known failure modes

- Empty results if search term matches no active Kalshi markets
- Payment failure if USDC balance is insufficient for the $0.0085 per-call fee
- Rate limiting or API errors if the BlockRun routing layer is congested
- Malformed or missing query parameters returning 400-level errors
- Kalshi API downtime causing upstream failures

## How this service works

BlockRun lets AI agents use money well: pay for results, not for seats or subscriptions, and put every cent on the model or tool that actually does the job.

## Output

Returns a list of Kalshi prediction market events and contracts matching the search query, including market titles, ticker symbols, contract details, and metadata about open markets available on the Kalshi platform.
