APIDistributed vs APILayer Marketplace

APIDistributed is a public, cloud-deployed marketplace for production APIs. It lets one API key reach APIs from multiple providers through a gateway that identifies the provider, checks plans, applies quotas, measures requests, and combines provider charges on one invoice. The homepage lists more than 4,200 APIs spanning AI and machine learning, data, payments, communications, maps, media, and finance. A single Bearer token works across marketplace endpoints. Typed clients are listed for Node, Python, Go, and Rust, with a cURL example. Per-call telemetry reports latency, cost, and status. Pay-as-you-go pricing starts at $0.0002 per call, and the first 100,000 calls each month are free forever; volume discounts apply. Spend caps and per-key budgets are available, with no minimums, seats, or idle fees. API publishing, subscriber billing, and marketplace analytics are supported. The service is in private beta and invites early-access requests.
