Momentum radar for the x402 seller ecosystem - which sellers are heati
Momentum radar for the x402 seller ecosystem - which sellers are heating up, graded for wash-trade resistance. Reads the hourly on-chain leaderboard (real Base USDC settlements) and adds per-seller signals the raw board doesn't have: organicScore (uniqueBuyers/callsSettled - 1000 calls from 2 buyers smells like self-dealing, 1000 from 400 is organic demand) and avgTicketUsd.
Safety verdict for one Solana token mint: a graded risk score with the
Safety verdict for one Solana token mint: a graded risk score with the concrete reasons behind it, mint and freeze authority state, how much of the liquidity pool is locked, top-holder concentration, holder count and whether the token is verified. Use it before an agent buys, quotes, or recommends an unfamiliar token, and to screen a list of mints in seconds.

OpenAI Responses API billed per request from what the call costs: the 402 quotes exact-BPE input (instructions + input items + tools) plus your max_output_tokens at the model's list price, times 1.15, never under $0.001; an upto (Permit2) or credits buyer settles actual usage under that quote.

Plexa /v1/pretrade/check — pre-trade token safety check on Base: can you still sell this token? avoid fires only on a trap proven on-chain now: no pool to exit into, an exit pot under 5% of your size, or the trading gate off (the honeypot shape). A drained pot is what a rug leaves behind — measured, not predicted. clear = no provable trap, NOT safe. risk_profile: token age, holder concentration, liquidity, transfer limits. Not financial advice.
