INTRODUCING MERCATOR by @tempo. Mercator gives agents a new effort level. By giving an agent a search engine to the world's paid tools it empowers a small model to punch above its weight, while being cheaper than larger models. $5 Mercator credits w/ your X/Github ⬇️

New design. Still the future of payments. Agentic commerce is continuing to evolve and it's only right MPP does too.

Your agent needs data it can actually work with. Pulse handles that; turning complex documents like financial statements, contracts, and claims into clean markdown and structured data for agents. With MPP, agents can access and use Pulse via API. No accounts needed:

Agentic payments are now live on @Pulse__AI . An agent can point at our API with no account, no API key, and no signup, and pay for extraction on its own, one call at a time. It runs on the Machine Payments Protocol (MPP), settling inline over HTTP in USDC, in the same request
