Felo APIs

Felo APIs Overview

Felo workflows under /v2, called with Felo Pro credits. Compare them with platform-balance APIs.

To pay for web search, web reading, X data, Chat or PPT with platform balance, use Felo in Data API. This page documents the existing /v2 APIs, which use Felo Pro credits.

Felo APIs are first-party, workflow-level APIs for search, documents, presentations, web extraction, social search, and agent workflows. They use the same Felo API key as the rest of the platform, but are billed separately from model calls.

Eligibility can change. The Console Billing page is the source of truth for your current balance and usage.

Billing model

SurfacePathHow calls are paid
Felo APIs/v2/*Felo Pro credits
Felo in Data API/api/v1/data/*Platform balance, not Pro credits
Model API/api/v1/*Prepaid Felo API Platform service credits only; Felo Pro does not apply
Data API/v1/beta/*Uses the API catalog billing basis shown for each endpoint

Felo Pro credits and API service credits are separate balances. A Felo Pro subscription does not automatically grant API service credits, and API service credits do not add Felo Pro subscription credits.
