Pre-flight an x402 payment: decode the endpoint's challenge, report the cost on every rail (Base and Solana) and the cheapest, and — with a payer address — verify the wallet can afford the call on Base.
# 1. Ask the endpoint what it costs (no payment, no wallet needed): curl -i -X GET 'https://quartermaster.surewhynot.app/v1/x402/simulate' # -> HTTP/1.1 402 Payment Required # the response carries the price, asset and pay-to address. # 2. Pay and retry with any x402 client: npx x402-fetch 'https://quartermaster.surewhynot.app/v1/x402/simulate'

Verify an x402 settlement on Base OR Solana: pass a 0x transaction hash or a base58 signature, confirm it succeeded, decode its USDC transfers (event logs on Ba…
Pick one or several options at random from a caller-supplied list (CSPRNG), optionally without replacement — a decision-maker for agents.
Cryptographically-secure random integers in a chosen range (CSPRNG, rejection-sampled to avoid modulo bias) — real entropy an LLM cannot produce itself.
Formatted settlement receipt for any Base transaction hash or Solana signature: timestamp, status, decoded token transfers, explorer link — records for x402 pay…
The x402 Router: send a plain-English goal in q (e.g. 'audit https://api.example.com/paid', 'price of eth', 'is 0x… a contract', 'verify settlement 0x…') and Qu…
