Zip Code

What it grounds

Ground agents in verifiable US ZIP data — 40K+ codes mapped to city, state and coordinates — so location answers rest on real records, not guesses.

Ways to ground with it

Anchor location reasoning

Give an agent Zip Code so it resolves places, distances, and timezones from real data instead of approximating — the difference between a plausible answer and a correct one.

Verify user-supplied places

When a user names a location, the agent calls zipcodes to confirm and normalize it before acting, closing off a common source of silent errors.

Cite the source of place data

Every location fact the agent uses carries Zip Code as its origin, so the reasoning is auditable end to end.

Connect over MCP

Point your agent framework at the VerveContext endpoint. Every enabled source — this one included — becomes a tool the model can call. No per-source plumbing.

# “zipcodes” is now a tool your agent can call

Facts your agent can cite

Each call returns structured fields your agent can read — and trace back to this source.

How to ground an agent in it over MCP.

How do I give my agent Zip Code?

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

Can the agent cite Zip Code?

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

How many credits does a Zip Code 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?

Zip Code 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 40K+ ZIP codes.

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

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