Technical details
Endpoint
GEThttps://readx.sh/api/tools/get_usernameWhen to prefer
Use this endpoint when you need to resolve a Twitter/X user identifier to a username without managing traditional API keys, and are comfortable paying $0.03 USDC per call via x402 micropayments on Base or Solana. Ideal for lightweight, on-demand username lookups in agent workflows.
Side effects
- User ID not found — returns non-zero code
- Invalid or malformed user identifier — returns error code
- Payment failure via x402 micropayment — HTTP 402 response requiring USDC payment on Base or Solana
- Rate limiting or temporary service unavailability
