Pay-per-call data API for AI agents: AI model prices and cost calculator, 4,259 MCP servers, email domain checks, text-to-JSON extraction, country/holiday/currency lookup, page and link checks, page-to-markdown, 2,230 verified APIs. x402, USDC on Base, no signup. Sources cited in every response.

A JSON object containing an array of rows (up to 2,230 API records with metadata), a count field (2230), and a license field indicating 'CC BY 4.0 (compilation) + MIT (public-apis source)'. Each row describes a verified public API with relevant attributes.

Endpoint
GEThttps://freetier-agent-api.pages.dev/api/dataset/full?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a broad, pre-verified catalog of 2,230 public APIs with licensing metadata in a single call. Ideal for agent bootstrapping, API discovery pipelines, or building a developer directory. Prefer this over web scraping API lists because the dataset is curated, verified, and comes with citation sources. The x402/USDC pay-per-call model means no signup friction for agents.
Side effects
- Payment not received or insufficient USDC — returns HTTP 402 with payment required details
- Invalid filter properties in query — may return empty rows or schema error
- Network timeout on large dataset retrieval
- Rate limiting or access restriction if payment fails on Base network
