# Vimmerse Free Seller API Quote and Purchase Guide

> Vimmerse Free Seller API Quote and Purchase Guide is a free API for AI agents from agents.vimmerse.net, callable via x402, Free, status unknown (last checked 2026-10-31).

## 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 agents-vimmerse-net-vimmerse-free-seller-api-quote-and-purchase-guide-07805c68 -d '<json body>'
```

Example prompt: Before I spend anything, can you get me a free quote from Vimmerse for generating a 30-second AI video from a text prompt — I have a $10 budget and plan to make about 5 calls?

## When to prefer this

Use this endpoint before making any paid Vimmerse API call when you want to confirm the exact contract, price, and prerequisites without spending money or needing a wallet. Prefer it over browsing /openapi.json directly when you want a natural-language task description matched to the right endpoint with step-by-step guidance. Also use it when operating without a wallet or crypto identity, as it works wallet-free via /zeroclick/agent/guide.

## Known failure modes

- 'needs_input' status returned when the goal description is too vague to match a specific API contract
- 'unsupported' status if the described task has no matching Vimmerse capability
- 'unavailable' status if the catalog or backend service is temporarily unreachable
- 'blocked' status if the request is rejected due to policy or content constraints
- Malformed goal string (empty or exceeding 2000 chars) causes a 400 validation error
- Invalid budgetUsd format (non-numeric or wrong pattern) causes schema validation failure

## How this service works

Describe your task to get the matching API contract, prices, prerequisites and next steps. This is a $0 wallet-proof lookup, not the seller's paid service. No purchase is executed. Without a wallet, use /zeroclick/agent/guide.

## Output

Returns a JSON object with: a status enum (quoted, catalog, ready, needs_input, blocked, unknown, unsupported, unavailable), a priceUsd always set to '0' (this lookup is free), a markdown 'guide' string with the matched API contract, exact pricing, prerequisites and recommended next steps, and a 'guideUrl' URI pointing to a wallet-free advisor endpoint for further planning or recovery.
