How this service works
Buy a blockmachine API key with Request Unit (RU) credit. blockmachine is decentralized multi-chain RPC infrastructure on Bittensor Subnet 19 - one key authenticates across supported chain RPC endpoints (Bittensor and Ethereum), spending from a single global RU budget. Pay per purchase in USDC (Base), TAO, or alpha.
Output
Returns a newly created API key credential that can be used to authenticate subsequent requests to BlockMachine services, along with any associated metadata such as key ID, creation timestamp, and permissions scope.
Example use cases
Example prompt
“Create a new API key for my BlockMachine account so I can start making authenticated API calls — I'm ready to pay the $5 USDC fee via x402.”
Technical details
Endpoint
POSThttps://blockmachine.io/user-management-api/x402/api-keys?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically create or provision API keys for BlockMachine services, especially when operating within the x402 payment protocol ecosystem. Prefer this over manual key generation when automating developer onboarding or integrating BlockMachine into an automated workflow.
Side effects
- Payment of $5 USDC fails or is rejected by x402 protocol — returns payment required error
- Invalid or missing user account credentials — returns authentication error
- Duplicate key creation attempt — may return conflict error
- Rate limiting on key creation — returns too many requests error
- Malformed request body — returns 400 bad request with validation details
