Technical details
Endpoint
GEThttps://x402-seo-api.restockalarm.workers.dev/v1/keyword-ideas?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, pay-per-use SEO keyword ideation without committing to a subscription-based keyword research platform. Ideal for agents that need to generate keyword suggestions on demand for a specific seed term, especially in automated content pipelines or low-volume workflows where per-call micropayment (via x402 on Base) is more economical than a monthly SaaS plan.

- Keyword exceeding 100 characters may be rejected
- Payment failure via x402 if wallet has insufficient USDC on Base
- Rate limiting or worker timeout if the upstream data source is unavailable
- Unsupported language code may fall back to English or return an error
