I-Bond Rate

What it grounds

Ground agents in verifiable US Treasury I-Bond rates — composite, fixed and inflation, back to 1998 — so savings answers cite real data.

Ways to ground with it

Stop stale-number hallucinations

An agent asked about prices or rates will happily invent a figure. Enable I-Bond Rate and it calls the savingsbonds 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 I-Bond Rate as its origin, so a human can trace where the number came from.

Fresh at answer time

Because the model pulls i-bond rate at the moment it responds, the answer reflects the market now — not whatever was true when the model was trained.

I-Bond Rate, answered

How to ground an agent in it over MCP.

How do I give my agent I-Bond Rate?

Enable it on VerveContext and point your agent framework at the VerveContext MCP endpoint. I-Bond Rate then appears to the model as a tool named savingsbonds, 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. I-Bond Rate is exposed as a standard tool, so nothing source-specific is required.

Can the agent cite I-Bond Rate?

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

How many credits does a I-Bond Rate 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?

I-Bond Rate 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 1998.

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

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