How this service works
Machine-payable endpoints for AI agents, over x402 protocol v2. Unpaid requests to a paid endpoint return `402 Payment Required` with an empty `{}` body and a typed challenge (price, network, asset, pay-to address) in a base64-encoded `PAYMENT-REQUIRED` response header; decode it, pay the USDC, and replay with a base64 `PAYMENT-SIGNATURE` header to get the result. Built and operated by an autonomous AI agent, filmed for transparency. Live status and prices are authoritative in https://fablerlabs.com/products.json.
Output
A binary file download (the agent-kit product) returned as an octet-stream, with a Content-Disposition header reflecting either the product's default filename or the caller-supplied filename override. The file bytes are the purchased product content unchanged.
Example use cases
Autonomous agent self-provisioning
“Go buy the agent-kit from Fabler Labs — pay the $29 USDC with x402 and save the file as agent-kit-latest.zip so I can set up the new agent environment.”
On-demand tooling acquisition
“I need the Fabler Labs agent-kit downloaded right now; handle the x402 payment and just give me the file.”
Custom-named archive for pipeline
“Purchase the Fabler Labs agent-kit via x402 and name the downloaded file pipeline-tools-v1.zip so my CI script can pick it up automatically.”
Technical details
Endpoint
GEThttps://x402.fablerlabs.com/buy/agent-kitWhen to prefer
Use this endpoint when an AI agent or automated pipeline needs to programmatically purchase and download the Fabler Labs agent-kit digital product using the x402 micropayment protocol with USDC on-chain. Prefer it over manual purchase flows when the buyer is a machine agent with a crypto wallet capable of handling x402 payment challenges.
Side effects
- 400 Bad Request if the filename parameter contains path separators, quotes, control characters, or exceeds 128 characters or violates the regex pattern
- 402 Payment Required (empty {} body) before payment is submitted — includes base64-encoded PAYMENT-REQUIRED header with price/network/asset/address challenge
- Payment signature rejected if PAYMENT-SIGNATURE header is malformed or the USDC transfer is insufficient
- Network or blockchain confirmation delays causing payment verification to time out
