Do not pay until the binding, price, network, asset, payTo, and expiry match local policy.
Prepare an HTTP purchase request for deterministic JSON verification after a successful free precheck; a prior quote tool call is optional. After a successful free precheck at POST /validate-request, supply the unchanged intent and its precheck_receipt.receipt_digest. Creates or reuses a persisted quote and records observability events; no payment, signing or paid verification is performed. The bound quote ties request/evidence digests, precheck digest, spend policy, quoted amount, network, asset, recipient and expiry together. Server availability, fresh cost basis and conservative contribution-margin thresholds must pass. Returns JSON text and structuredContent containing quote, request (POST /verify-evidence, content-type and X-Quote-ID headers, unchanged intent body), expected_first_status=402 and expected_payment_header=PAYMENT-REQUIRED. It does not send this request. Application failures return isError=true with JSON error.code, message, retryable and optional details (for example PRECHECK_STALE, PRICE_CAP_EXCEEDED, IDEMPOTENCY_KEY_CONFLICT, IDEMPOTENCY_KEY_EXPIRED or UNPROFITABLE_TRANSACTION); invalid argument shapes are rejected by MCP schema validation. Re-run precheck after request/policy changes; do not pay on refusal. Next send the returned request to obtain a challenge, check binding, amount, network, asset, payTo and expiry against local policy, then authorize payment separately. Use quote_verify_evidence when only quote terms are needed.

Obtain a free bound quote for deterministic checks on supplied JSON before deciding to purchase. After a successful free precheck at POST /validate-request, supply the unchanged intent and its precheck_receipt.receipt_digest. Creates or reuses a persisted quote and records observability events; no payment, signing or paid verification is performed. The bound quote ties request/evidence digests, precheck digest, spend policy, quoted amount, network, asset, recipient and expiry together. Server availability, fresh cost basis and conservative contribution-margin thresholds must pass. Returns the quote as JSON text and structuredContent: quote_id, request_hash, price (atomic USDC, 6 decimals), expires_at, economic_guard, purchase instructions and paid_verification_binding in state quoted, not a paid receipt. Application failures return isError=true with JSON error.code, message, retryable and optional details (for example PRECHECK_STALE, PRICE_CAP_EXCEEDED, IDEMPOTENCY_KEY_CONFLICT, IDEMPOTENCY_KEY_EXPIRED or UNPROFITABLE_TRANSACTION); invalid argument shapes are rejected by MCP schema validation. Re-run precheck after request/policy changes; do not pay on refusal. Next use prepare_verify_evidence_purchase with the same key and intent for the HTTP purchase request, or explicitly authorize the separate paid verify_evidence flow.
