# LupaPlaza Accepts Probe

> LupaPlaza Accepts Probe is a paid API for AI agents from lupaplaza.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Returns LupaPlaza's live accept-selection policy, documenting which payment assets and schemes are accepted for API calls (Exact+Base, no automatic conversion or second-rail fallback).

## 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 lupaplaza-accepts-probe-8637024c
```

Example prompt: Check LupaPlaza's current accept-selection policy so I know exactly which asset, network, and payment scheme to use before submitting a paid API call.

## When to prefer this

Use this endpoint when an AI agent or developer needs to programmatically discover LupaPlaza's current payment acceptance policy before initiating a paid API call. It is the authoritative source for which asset (Base USDC), network (eip155:8453), and scheme (exact) to use. Prefer this over hardcoding payment details, especially when building automated agents that must handle payment negotiation correctly without assuming fallback rails or automatic conversion exist.

## Known failure modes

- HTTP 402 if the probe call itself is not paid correctly
- Stale or outdated policy if attested_at timestamp is old
- Single live candidate with no fallback — if client cannot pay Base USDC exact, no alternative is offered
- Malformed response if the service is temporarily unavailable
- No schema validation on the optional 'properties' input parameter may result in unexpected behavior

## Output

A JSON object containing the product name, ruleset version, attestation timestamp, auto-conversion status (false, with explanation), payment-routing status (false, with explanation), and an acceptance_policy listing live payment candidates — each with asset contract address, amount, scheme (exact), network (eip155:8453/Base), and primary flag. Also includes fallback policy explaining no alternative is available if the listed accept is incompatible.
