# FAQ

> Common questions about Kviria - coverage, integration, pricing, and behavior.

## Where does Kviria work?

Kviria is in beta and covers San Francisco (approximately lat
37.70-37.84, lng -122.54 to -122.36). Queries outside the covered
area return an honest `notFound` - never a guess. More areas are
planned.

## How do I integrate Kviria?

One HTTP endpoint: `POST /v1/agent`, authenticated by your wallet
(the `SIGN-IN-WITH-X` header — a CAIP-122 sign-in, no key to
provision). Send the user's raw transcript or a structured intent,
plus their anchor. MCP clients can connect the
[MCP server](/api/mcp) instead. The full contract lives at
[kviria.com/skill.md](https://kviria.com/skill.md) - your agent can
load it directly.

## Is Kviria another AI model?

No. Kviria complements your model. Your LLM maps the user's words;
Kviria executes deterministically and returns data only - names,
distances, categories, coordinates, and an evidence trail. It never
writes the user-facing reply.

## What happens when a reference is ambiguous?

Kviria never guesses. Several matches come back as `candidates`, and
your agent asks which one. A single survivor is held at a
[confirm gate](/how-it-works/confirm-gate) until the user verifies it -
the coordinate is released only after their yes.

## How much does it cost?

Your first 50 turns each day are free. Beyond that, turns settle at
\*\*$0.005 each** from a prepaid USDC balance on Base (minimum top-up
$1). See [Payments](/api/payments) and
[Rate limits](/api/rate-limits).

## Do I need an API key?

No. Your wallet is your account: every call carries a wallet sign-in
(the `SIGN-IN-WITH-X` header). The `x-kviria-agent` flag is a
namespace label that keeps your context separate from other agents -
it is not a secret and not an authentication credential.

## Does Kviria store my conversation?

No. Kviria holds no conversation memory. You keep the state and echo
the relevant parts back on each call - see
[Echo state](/how-it-works/echo-state).
