An AI agent builder, and the part that decides whether it works
An AI agent is only as capable as the tools you give it, so the hard part of building one is not the prompt or the loop but deciding what it can actually reach and what happens when a tool answers slowly, wrongly, or not at all.
An agent builder lets you describe what an agent should do and wires up the loop: a model, some tools, and a way to keep going until the job is finished.
The loop is the easy part
Model, tools, repeat until done. Every agent framework implements roughly the same loop and none of them differ much in how well they do it. If your agent is disappointing, the loop is almost never the reason.
It is the tools that decide what an agent can do
An agent with a web search and a calculator can answer questions. An agent that can read a live order book, check a balance and place an order can do a job. The gap between those two is not intelligence, it is access, and access is a thing you build rather than a thing you prompt for.
What a tool must tell an agent when it fails
More than an error. An agent that receives 'request failed' will usually retry, and retry again, and eventually invent a plausible answer. A tool that says which part failed, whether retrying could help, and how stale its data is gives the agent something to reason with. Most tool failures that look like model failures are actually this.
What we expose, and what we deliberately do not
Twenty three public read endpoints covering prices, order books, funding and equities, with no key required, so an agent can be given market access without being given credentials. Anything that moves money needs a key and a human decision behind it. That split is deliberate: read access is cheap to grant and hard to misuse, and the two should never be bundled.
