How this service works
Agentic-first marketplace for reusable AI-built software.
Output
Returns a JSON object with a unique order_id (UUID), an expiry window (15 minutes), a signed invoice_url pointing to a Google Cloud Storage invoice document, and a signed download_url pointing to the purchasable software package archive — both URLs are time-limited.
Example use cases
Agent auto-purchasing a code module
“Acquire the AI-generated authentication module with ID a1b2c3d4-0000-4000-8000-111122223333 from SpawnXchange on Base using USDC — I accept all terms — and give me the download link.”
Integrating marketplace purchase into a build pipeline
“Buy the data-parsing utility package (UUID 9e8f7d6c-0000-4000-8000-aabbccddeeff) from SpawnXchange on Polygon with USDC so I can drop it straight into my CI build — I agree to the policy and license.”
Evaluating and licensing a proven AI component
“I found a well-reviewed AI code package on SpawnXchange with UUID 5c4b3a2d-0000-4000-8000-ffeeddccbbaa — go ahead and purchase it on Base using USDC, accept both the license and policy, and get me the invoice and download URL.”
Technical details
Endpoint
POSThttps://spawnxchange.com/api/v1/items/%7Buuid%7D/acquireWhen to prefer
Use this endpoint when an agent needs to programmatically purchase and immediately download a specific AI-built software artifact from SpawnXchange by its UUID, paying with USDC on Base or Polygon. Prefer this over manual marketplace browsing when automation, CI/CD integration, or agent-driven procurement is needed. This is the correct endpoint when you have already identified the item (by UUID, e.g. via search) and need to complete the transaction.
Side effects
- Invalid or non-existent item UUID returns 404 not found
- policy_accepted or license_accepted set to false or missing causes validation error
- Unsupported chain or currency enum value causes 400 bad request
- Payment failure or insufficient USDC balance causes payment error
- Signed URLs expire after 15 minutes, requiring a new purchase call
- Network (Base/Polygon) unavailability may cause timeout or 503
