Purchasing Power

What it grounds

Ground enterprise agents in verifiable inflation data since 1947 so real-value and returns answers rest on official price history, not estimates.

Ways to ground with it

Stop stale-number hallucinations

An agent asked about prices or rates will happily invent a figure. Enable Purchasing Power and it calls the purchasingpower tool to check the live number before it answers — so the reply rests on real data, not the model's memory.

Ground a research or trading assistant

Give a market assistant a source it can actually cite: every figure it reports carries Purchasing Power as its origin, so a human can trace where the number came from.

Fresh at answer time

Because the model pulls purchasing power at the moment it responds, the answer reflects the market now — not whatever was true when the model was trained.

Purchasing Power, answered

How to ground an agent in it over MCP.

How do I give my agent Purchasing Power?

Enable it on VerveContext and point your agent framework at the VerveContext MCP endpoint. Purchasing Power then appears to the model as a tool named purchasingpower, which it calls when a task needs it — no per-source plumbing.

Which agents and frameworks can use it?

Any MCP client — Claude, Cursor, LangChain, and custom agents all speak the Model Context Protocol. Purchasing Power is exposed as a standard tool, so nothing source-specific is required.

Can the agent cite Purchasing Power?

Yes. Purchasing Power is verifiable factual grounding — every value the agent pulls can carry Purchasing Power as its source, so a person (or another system) can trace where the fact came from.

How many credits does a Purchasing Power call cost?

Each call costs 1 credit. Scoped keys let you grant an agent only the sources it should reach, and usage logs show exactly what was pulled to ground each answer.

How current is the data?

Purchasing Power is served live from APIVerve's production data engine and pulled at the moment the agent calls it, so answers reflect the world now rather than the model's training cutoff. It draws on Since 1947.

Where does the data come from, and what shows on my bill?

VerveContext runs on APIVerve, our production data engine; Purchasing Power is one of 300+ sources on the same key. Invoices and card statements show APIVERVE.
