## When to prefer this

Choose this endpoint when an agent needs on-demand salary or compensation data without setting up a subscription or API key — ideal for pay-per-use workflows where the agent pays in USDC via x402. Best for job negotiation research, hiring budget planning, or career exploration queries where a natural language question about a role is sufficient input.

## Known failure modes
