Header Map Normalize API for agents
Lowercase HTTP header keys and drop hop-by-hop headers — first-party local utility for agent preflight and proven micro-utils expansion. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, no web search, no live RPC, and no mediagen. Results are advisory; the caller owns authorization, budgets, and production controls. Sibling of Delx routes that already converted externally (random, hash, URL, FX families).
Intent to transaction
One command, attributed.
The source header follows this discovery route through challenge, payment and delivery without exposing the buyer or request body.
