Tempo has launched **Mercator**, a tool router that lets AI agents find, pay for, and use outside services on demand instead of requiring developers to configure every tool in advance. 

### What’s the Scoop?

- **Tools on demand:** With **[Mercator](https://tempo.xyz/developers/blog/introducing-mercator)**, an agent simply describes what it needs and its budget. Mercator then searches available services, ranks them by fit, reliability, and cost, and executes the selected workflow. 

- **The agent multi-tool:** The idea should be familiar. [**MPP already launched with a directory**](https://www.bankless.com/es/read/stripes-tempo-makes-its-case), while we’ve seen a series of similar “agent multi-tools,” including [**AgentCash**](https://www.bankless.com/read/the-micropayments-breakthrough) and [**Pay.sh**](https://www.bankless.com/es/read/the-week-solana-brought-google-to-x402), that give agents one place to discover and pay for outside APIs without separate accounts or keys. Mercator pushes this model further: rather than just helping an agent find and access a tool, it can rank services and combine multiple paid tools into a single workflow. 

- **One payment layer:** Mercator connects agents to services using open payment standards MPP and x402, while users pay Mercator itself primarily with MACH, a USD-denominated Tempo credit purchasable through Apple Pay. It also supports USDC.e and pathUSD payment routes, handling payments to downstream services behind the scenes. 

- **Making smaller models better:** Tempo says Mercator improved model performance across all four benchmarks it tested, with the largest gains coming from cheaper models. GPT-5.6 Luna at high effort, for example, improved from 66.8% to 70.3% across the benchmark suite with Mercator, putting it within 2.3 points of GPT-5.6 Sol at medium effort without it.
