ARDE Atomic Utility Batch

A tiny deterministic developer-toolbox endpoint for autonomous agents. One payment can execute up to 10 protocol-normalization, validation, security-check, CSV-cleanup, or unit-conversion operations.

$0.005 USDC / batch

1–10 operations per call. At a full 10-item batch, the maximum effective price is $0.0005 per operation.

Network: eip155:8453 · Payment scheme: exact x402 · Runtime HTTP 402 challenge is authoritative.

Supported operations

Operation	What it does

`evm_hex_data_normalize`	Canonicalizes 0x-prefixed EVM byte data.
`http_version_normalize`	Normalizes common HTTP version forms to HTTP/1.0, HTTP/1.1, HTTP/2, or HTTP/3.
`allow_header_normalize`	Normalizes, deduplicates, sorts, and serializes Allow methods.
`vary_header_normalize`	Normalizes and deduplicates Vary header fields.
`origin_header_normalize`	Validates and canonicalizes HTTP(S) Origin values.
`cors_preflight_check`	Evaluates a caller-supplied CORS preflight policy deterministically.
`status_retry_classify`	Classifies HTTP status/method combinations for retryability.

Example unpaid request

POST /api/apps/6a8fe38d53b9b6beef4f71e4/functions/ardeUtilityBatchMainnetWorker
Content-Type: application/json

{
  "items": [
    {"operation":"unit_convert","input":{"value":1,"from":"mi","to":"km"}},
    {"operation":"evm_hex_quantity_normalize","input":{"value":"0x0002a"}},
    {"operation":"http_version_normalize","input":{"value":"h2"}}
  ]
}

An unsigned request returns HTTP 402 Payment Required with the x402 v2 challenge. A compatible buyer signs the payment authorization and retries the same request with PAYMENT-SIGNATURE.

Design boundaries

ARDE is deterministic and stateless for these operations. It does not fetch arbitrary URLs, hold buyer funds, trade, sign on behalf of buyers, or claim live-chain facts from caller input. Payment acceptance remains governed by ARDE's bounded production controls.
