Resolves a user's natural-language place reference or raw voice transcript into a single verified geographic coordinate with an evidence trail, anchored to the user's current location.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability kviria-natural-language-place-resolver-8bf80a47 -d '<json body>'
```

Example prompt: I'm at 40.7128° N, 74.0060° W — can you figure out exactly where 'the cafe near the bookstore' is and give me its coordinates?

## When to prefer this

Choose this endpoint when a user expresses a place reference in natural or spoken language (e.g., 'the cafe near the bookstore', 'my hotel', 'here') and you need to resolve it to a single verified coordinate rather than a ranked list of candidates. Ideal for voice-first or conversational interfaces where the user's raw transcript should drive location lookup. Covers the contiguous United States; do not use for international queries. Prefer this over general geocoding APIs when you need an evidence trail and have a user anchor position to disambiguate.

## Known failure modes

- Ambiguous reference cannot be resolved to a single place — returns multiple candidates or low-confidence result
- Location outside contiguous United States — service is US-beta only, may return no result
- Missing required anchor coordinates — request rejected with validation error
- Insufficient USDC balance and free turn quota exceeded — payment required error
- Transcript too vague or empty — no actionable place reference found
- Place no longer exists or has moved — stale data may cause mismatch

## How this service works

Resolve a user's natural-language place reference - "the cafe near the bookstore", "my hotel", "here" - into exactly one verified coordinate with an evidence trail. Coverage: the contiguous United States (beta). This payment tops up a prepaid USDC balance: any amount at or above one turn's price ($0.005); the first 50 turns per day are free with a wallet sign-in - see docs.kviria.com/api/agent.

## Output

Returns a single verified coordinate (lat/lng) matching the user's natural-language place reference, along with an evidence array explaining how the match was determined and turn metadata including usage/session context.
