https://three.ws/api/x402/symbol-availability
three.ws Symbol Availability — given a candidate ticker symbol, check for exact and fuzzy collisions across pump.fun mints indexed by three.ws. Returns exact matches (same symbol on the same network) plus trigram-similar symbols (e.g. "USDC" vs "USDCC", "PUMP" vs "PMP"). Use before launching a token to avoid name confusion and aggregator-search dilution.
Start with a quote-only recipe. Payment signing stays in your project.
const response = await fetch("https://three.ws/api/x402/symbol-availability", {

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
