How this service works
A live, working x402 v2 server demonstrating both ways to pay over HTTP: a machine paying an agent-facing API for data, and a human paying for content from a browser wallet. A reference implementation and participation experiment — not a product. Each paid request settles on-chain and returns payment evidence.
Output
An array of AWS Lambda runtime identifier strings (e.g. ['nodejs22.x', 'python3.13', 'java21', 'provided.al2023']) representing all runtimes currently available on the Cloudless platform.
Example use cases
Pre-deployment runtime compatibility check
“Before I deploy my serverless function to Cloudless, can you check which Lambda runtimes they support so I know if Node.js 22 is available?”
Choosing a runtime for a new project
“I'm starting a new serverless project on Cloudless and need to pick a language — can you pull up all the supported Lambda runtimes so I can decide between Python and Java?”
Verifying custom runtime availability
“Does Cloudless support the provided.al2023 custom runtime for AWS Lambda? Can you fetch their supported runtime list to confirm?”
Technical details
Endpoint
GEThttps://x402.cloudless.sh/v1/lambda-runtimes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover which Lambda runtimes are available on Cloudless before deploying or configuring a serverless function. Prefer this over guessing or checking documentation when you need a live, authoritative list of supported environments.
Side effects
- Payment failure: insufficient USDC balance or x402 payment protocol error prevents access
- Service unavailability: Cloudless platform down, returning 5xx errors
- Empty list returned if no runtimes are currently configured or supported
