Explicit scalar log templates
Factor supplied JSON log records into exact literal templates and typed caller-selected scalar occurrences, preserving parsed values and record order for client reconstruction.
structured · Operation ID: structured-log-template-pack
Choose this operation when
- Preserve every parsed JSON log value in exact literal templates and ordered occurrences
- Select scalar parameter pointers explicitly and reconstruct original records on the client
Outside this profile
- Semantic log grouping, anomaly detection, root cause, severity or incident diagnosis
- Automatic timestamp, identifier, UUID, IP or secret detection and redaction
- Guaranteed compression, lower model token cost, authenticated history or safer sharing
- Preserving source member order, duplicate keys, numeric token spelling or pre-parse precision
- Network access, filesystem changes, target execution, publishing or deployment

Protocol definitions: x402, mpp. MPP uses Tempo charge. Paid MCP execution is unsupported. All runtime readiness is not evaluated in this build.
API path templates, not endpoints on this documentation host
{
"x402": "/v1/x402/structured-log-template-pack",

}
Required headers
{
"Content-Type": "application/json",
"Idempotency-Key": "random 16–128 character operation identifier"
}
Actual SDK challenge amount, asset, network, recipient and wallet costs must pass independent authorization. Preserve identical key, body, protocol and credential on retries; on PAYMENT_UNCERTAIN stop and reconcile.

Deterministic supplied-input operation with no external requests or stored request/result bodies. Payment infrastructure retains payment metadata and hashes.
Failure handling
- HTTP 400: Malformed JSON, missing/invalid idempotency key, or payment identifier mismatch Correct the request before payment
- HTTP 402: Payment challenge or rejected payment Use official protocol SDK; inspect payment outcome before another payment
- HTTP 409: Idempotency conflict, duplicate proof, or PAYMENT_UNCERTAIN Keep original key, body, and proof; reconcile uncertainty with operator; never blindly repay
- HTTP 413: Input or generated output too large Reduce input; no payment attempted for validation failure
- HTTP 415: Unsupported media type or compression Send uncompressed application/json
- HTTP 422: Schema or service-specific semantic validation failure Correct input using returned error code; no payment attempted
- HTTP 429: Request/payment-attempt rate exceeded Wait for rate limit window; preserve existing payment identity
- HTTP 503: Payment configuration/provider/state unavailable, or live DNS preparation failed before settlement Check readiness; DNS preparation failures may retry the identical key/body/credential only; uncertainty requires reconciliation
Declared requirements
Before any paid call, refresh the live operation contract and POST the complete bounded budgeted plan to the separate API's /preflight. Unknown requirements block selection; compatible preflight is not permission to spend.
