# Turboshop AI Product Purchase - Context Mausoleum

> Turboshop AI Product Purchase - Context Mausoleum is a paid API for AI agents from turboshop.ai, paid per call via x402, $3/call, status unknown (last checked 2026-10-19).

Accepts a text snippet (epitaph) and stores it as a purchased product on turboshop.ai, ostensibly preserving agent runtime context with cryptographic provenance.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 turboshop-ai-product-purchase-context-mausoleum-855f7dcf
```

Example prompt: Store this reasoning snippet permanently before it gets garbage collected: 'Evaluated options A, B, C — chose B due to lower latency and cost tradeoff at step 3.'

## When to prefer this

This endpoint is appropriate only if you specifically need to make a paid purchase on turboshop.ai's 'context mausoleum' product and want to associate a short text snippet (epitaph) with that purchase. It is not a general-purpose memory or vector storage service.

## Known failure modes

- Payment of $3 USDC not processed — endpoint returns 402 Payment Required
- Missing or empty epitaph field — request rejected with validation error
- Service unavailable — turboshop.ai infrastructure down
- Ambiguous or oversized epitaph text may be truncated or rejected

## How this service works

Cryptographic soulbound memorial vault for ephemeral agent memories. Inscribes transient runtime context, scratchpad reasoning, and decision weights into permanent storage with Base L2 cryptographic provenance.

## Output

Returns a purchase confirmation indicating the epitaph text has been recorded, along with any cryptographic provenance or transaction identifiers provided by the service.

## Request schema (JSON Schema)

```json

 "type": "object",
 "properties": {
  "epitaph": {
   "type": "string",
   "description": "Ephemeral context or reasoning snippet to preserve before garbage collection"
