Scraper

Scrape any URL to clean, LLM-ready markdown in one call.

Send a URL and get its page content back as clean markdown (or raw HTML), with title and meta description. Results are cached and served from storage while fresh, so repeat lookups are fast. Ideal for content research, briefs and feeding pages into LLM pipelines.

FAQ

Simple answers for developers using the API.

Pricing & Balance

Every API endpoint has a fixed price in USD. Your requests are charged directly against your API balance, so you always know what each call costs.

No. Seonio does not use abstract credits for API pricing. You add dollars to your account and spend that balance directly on API usage.

No. Your API balance never expires, so you can use it whenever your workflows need it.

Paid API requests stop until you add more balance. This keeps spend predictable and prevents unexpected charges.

API & Integration

You can create and manage API keys from your account. Use your key to authenticate requests from your app, scripts, or internal tools.

Yes. Your dashboard shows your API usage and remaining balance, so you can track costs while building and running automated workflows.

Our support team responds to email inquiries within 1 business day. We can help with account, billing, and API integration questions.

We enforce a global rate limit per API-Key of 10 requests per second across all endpoints to ensure system stability. If you exceed this, our servers will return an HTTP 429 Too Many Requests status code. To handle this seamlessly in production, we recommend building rate-limiting logic or an exponential backoff (briefly pausing before retrying) directly into your application code.
