# Introduction — Data API

Felo endpoints are listed alongside other providers in their existing categories and use platform balance. See [Felo setup](/docs/data-api/guides/felo-overview). The shared prefix below applies to third-party providers; follow each endpoint's own request documentation.

Access web search, content extraction, research, financial and market data, social platforms, SEO analytics, creator data, and person and company enrichment through Felo. Authenticate with a Felo API key using Bearer authentication or X-API-Key. Availability depends on account permissions and available Felo credits. Apollo requires administrative permission. Usage, quota, cost and pricing fields in provider response payloads are provider metadata, not Felo account balances or billing records. Final charges follow Felo billing records. Examples are illustrative. Operation x-felo-pricing metadata is a reference snapshot at document generation, not an account quote or a guaranteed price or spending cap. Resource credits are not Felo credits. Reference multipliers must not be applied again to settled customer amounts.
