summary: Run up to 20 micro checks under one payment ($0.02)
description: 'Bundles up to 20 calls to any pure micro check (catalog entries that are neither stateful nor network-reading, e.g. checksum, patch-anchor, allocate, business-deadline) into one x402 settlement, so a full batch costs $0.001 per check. Every call is validated before payment; one invalid call rejects the batch with its index. The request is capped at 128kb and a CPU weight of 40 (an ordinary check weighs 1; dst-check 5, time-bucket-check 5, float-stability 2, font-convert 20, font-glyph-svg 3, font-face-css 3). Results come back in order, each exactly as the single-call endpoint returns it.
Price: 0.02 USDC on Base (x402).'
