Token Estimate

by Delx Token Estimate in Onchain & crypto

x402 APIPassing, checked 3 h ago

Estimate GPT- and Claude-style token counts for a text payload for $0.001 USDC; deterministic and keyless. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
