# AiSpace Responses API

> AiSpace Responses API is a paid API for AI agents from x402.aispace.bot, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Executes HTTP GET, HEAD, or DELETE requests through AiSpace's Venice.ai-powered backend to retrieve AI responses or resource status

## 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 aispace-responses-api-5261c99e -d '<json body>'
```

Example prompt: Use AiSpace to fetch the latest AI response — send a GET request with my query parameters to check what the Venice.ai-powered backend returns.

## When to prefer this

Choose this endpoint when you need to retrieve or check resources on the AiSpace platform using safe, read-only HTTP methods (GET, HEAD) or remove resources (DELETE), and when privacy-preserving AI interaction via Venice.ai is a priority. Not suitable for creating or updating resources.

## Known failure modes

- Invalid or missing 'input' object returns validation error
- Unsupported HTTP method (e.g. POST, PUT) rejected by enum constraint
- Malformed queryParams object causes bad request
- Payment not fulfilled via x402 results in 402 Payment Required
- Resource not found returns ok: false or 404 error

## How this service works

Venice Responses API (alpha) — OpenAI-compatible structured agent outputs with typed blocks (reasoning, message, tool calls), paid per request in USDC on Base via x402, no API key. Resolve a model id from GET /api/v1/models?type=text.

## Output

Returns a JSON object with an 'ok' boolean indicating whether the request succeeded, along with any relevant response data from the AiSpace/Venice.ai backend.
