For years, institutional-grade financial data was gated behind big budgets, negotiated contracts, and serious engineering. Accessible to institutions, out of reach for everyone else. That's changing — and the infrastructure making it possible is finally coming together.
The Gap Nobody Solved
For the past two years, everyone has talked about AI agents in finance. Here's the truth: they haven't truly worked.
Not because the AI wasn't capable — but because the infrastructure wasn't ready. Data lived behind manual credentialing. Payments required human approval. Every time an agent needed something new, the workflow stopped and waited. These weren't autonomous agents. They were assistants waiting for permission.
Closing that gap requires three things working in concert: data, programmable payments, and an open workspace that doesn't make you reinvent the wheel. No single firm can own all of that. But when the right pieces connect, the loop closes.
What viaNexus Brings to the Stack
viaNexus is a producer-consumer marketplace powered by universe-based pricing. 40+ datasets from providers like MT Newswires, Aiera, ExtractAlpha, and SavaNet, delivered through high-performance APIs and an agentic services layer called vAST.
vAST handles agent-to-data authentication autonomously. The agent determines what it needs, accesses the right datasets, and keeps operating — no credential re-entry, no manual approvals, no broken workflows. When paired with a programmable payments layer, agents can pay for data in real time as they consume it. When deployed into an open workspace, they reason across live data rather than just retrieve it.
The result: user asks a question, viaNexus delivers the data, billing is handled automatically, the agent returns the answer. One seamless workflow with whatever stack you're building in.
What It Looks Like in Practice
To make this concrete: we connected three pieces that each bring something distinct to the workflow. The demos below came out of a conversation over coffee, not a deep integration project or a formal paid partnership. Here's what we used:
- viaNexus — a producer-consumer data marketplace delivering 40+ datasets from providers like MT Newswires, Aiera, ExtractAlpha, and SavaNet through a single unified API and agentic services layer.
- OpenBB — an open, programmable financial workspace that renders viaNexus data as live charts, tables, and dashboards, and provides the environment for deploying AI agents.
- Paygentic — a programmable payments platform built for agentic workflows, handling per-action billing in real time as the agent consumes data.
A full research dashboard — real-time quotes, earnings, estimates, and live news from MT Newswires — built in minutes using viaNexus data inside OpenBB.
If this is what's possible in an afternoon, imagine what you could build with a week.
Connect a viaNexus token and you're immediately looking at rendered charts, live tables, and interactive dashboards — not raw JSON. Real-time quotes render as live charts. Earnings and Events Calendars surface confirmed dates, webcast links, and transcripts. TrueBeats EPS forecasts from ExtractAlpha sit alongside prior quarter actuals from SavaNet. MT Newswires streams real-time headlines filtered by ticker.
The result adapts to whoever is using it. An investor builds a morning portfolio dashboard. A founder shapes it into a monetized research product. An analyst collapses multiple tabs and spreadsheets into one clean interface. Same data layer, different application.
The workflow is straightforward. Open OpenBB, drop in your viaNexus endpoint and token, and the data is live. From there the agent handles the rest — querying datasets, building widgets, and reasoning across them in response to natural language prompts. When you need to top up, ask the agent directly in the workspace, follow the Paygentic link, add funds, and keep going. The whole thing stays in one place, and the agent never stops.
The viaNexus agent can integrate with Paygentic for seamless in-workflow billing. Type/billing to generate a payment link, top up your balance, and the agent picks up right where it left off — no interruptions, no re-authentication.
The Agent Is Just One Example
The viaNexus financial agent — built on the viaNexus Agent SDK — is a useful illustration of what's possible on top of this infrastructure. It's not the product. It's a demonstration of what the data layer enables.
It reasons across widgets rather than just reading them. Ask it to summarize weekly performance, compare consensus expectations to last quarter's actuals, or surface estimate revisions ahead of earnings. It can create widgets, analyze existing ones, and pull from the full viaNexus catalog to deliver what would otherwise take hours of manual work.
More importantly, it can watch markets for you. Tell it to alert you when anything in your portfolio forms a death cross, or moves more than X% in a day — and it sends a full data payload to your email the moment that condition is met. The data watches itself. That's not a feature. That's a different way of working.
Set a condition for an alert on any asset in your portfolio — here, a death cross on Apple — and the viaNexus agent emails you a full data payload the moment it's triggered. No manual monitoring required.
Every viaNexus subscription includes core datasets: 15-minute delayed pricing, filings, and basic fundamentals. Edge datasets — premium news, transcripts, expanded fundamentals — layer in seamlessly, and the agent incorporates them immediately once enabled.
Built for Anyone With an Idea Worth Building
This doesn't require a large engineering team. A solo developer, a three-person startup, a buy-side analyst who has never touched a data pipeline — everyone gets access to the same institutional-grade layer at a fraction of the historical cost.
viaNexus is the data layer. Plug it into your own app, build your own agent, wire it into an existing workflow. The API is the same either way.
The barriers are coming down. The only question is what you'll build when it happens.
