## When to prefer this

Choose this endpoint when you need pay-as-you-go job listings or hiring market data without a subscription, especially in autonomous agent workflows where API key management is impractical. Ideal for one-off market research queries or low-volume hiring intelligence tasks billed per request via USDC.

## Known failure modes

- Insufficient USDC balance causes payment failure and no data returned
- Overly broad or malformed query parameters return empty or unhelpful results
- Rate limiting if too many requests are made in quick succession
- Service may return stale data if underlying job sources haven't been refreshed recently
- Vercel cold-start latency may cause occasional slow responses

## How this service works

## Output

A response containing current job listings and hiring market data matching the query, including role titles, company information, and potentially salary ranges or market signals, returned as structured data.
