Nightmarket

Nightmarket is an API marketplace built for AI agents. Instead of negotiating contracts or managing separate API keys for every provider, users give an agent the Nightmarket skill once and let it browse a catalog of agent-ready services. The platform focuses on pay-per-call access, with USDC settled on-chain per request, which makes it useful for teams that want flexible usage-based spending rather than subscriptions or upfront commitments. Listings emphasize practical buying signals such as pricing, usage stats, and provider traction so agents can compare services before calling them. Nightmarket also supports the supply side: API providers can list endpoints, set per-call pricing, and monetize usage through the same marketplace infrastructure. Overall, it fits teams building agent workflows that need a shared service layer for discovery, payments, and API access in one place.

Use this tool if you:
- Want agents to discover and purchase third-party API access from a single marketplace.
- Prefer pay-per-use pricing with on-chain settlement instead of contracts or bundled subscriptions.
- Need a lightweight way to expose many services to an agent through one shared integration.
- Want marketplace visibility into provider pricing and traction before choosing a service.
- Plan to monetize your own API for agent consumption with per-call pricing.
