Etag Parse
Etag Parse: Etag Parse separates weak and strong entity-tag semantics from an ETag value from bounded caller-supplied values without an external provider. Call Etag Parse before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Etag Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.
One-command purchase

No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
