Scraper

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

Send a supported URL and get available page content back as clean markdown (or raw HTML), with available 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 endpoint has a published USD price or formula. Requests draw from the same included and Extra Usage balance as website and MCP actions.

Testing balance is spent first. Active subscribers then use included usage and Extra Usage expiring soonest. Every amount is displayed in dollars.

New Extra Usage is valid for one year. Included usage is replaced at each subscription-month boundary based on the active tier.

API & Integration

API actions require a verified account with a testing balance or active subscription balance. Create and manage API keys from your account, then send the key in the X-API-Key header.

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