Example prompt: Can you find me keyword ideas related to 'web design agency' in English for the US market — give me the top 10 results with search volume, CPC, and competition score?

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call keyword research without setting up an account or API key — ideal for AI agents that need on-demand SEO data with USDC micropayments on Base. Prefer this over subscription-based keyword tools when usage is sporadic or budget is usage-based. Best suited for agents building content strategies, running PPC campaigns, or conducting competitive SEO research at scale.

## Known failure modes

- Missing required 'keyword' field returns a validation error
- Invalid language_code or location_code may return empty results or an error
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Rate or quota limits may return a 429 or payment-required response
- Very niche or low-traffic keywords may return few or zero results
