summary: >-
  There is no separate test environment and no test-mode key: production is the sandbox, and every free read is
  already production data. What the provider publishes instead is a rehearsal path for the one thing that
  costs money — an x402 purchase: (1) every paid door answers a free 402 challenge that itself carries a free
  preview of the deliverable; (2) preview=true / omitting bundle=1 returns an unsigned free version of the
  artefact; (3) GET /api/free-door is a real x402 route priced at zero so a wallet can settle end-to-end and
  charge nothing. The dedicated /api/sandbox endpoint is declared retired ("sandbox — retired until its response
  can be derived from current evidence"), and the provider states that its own wallets' payments are recorded
  as self-tests and never counted as buyers.
test_vs_live:
  separate_environment: false
  key_prefixes: not applicable — no keys are issued
  test_network: none — x402 settles on Base MAINNET (eip155:8453); the zero-amount door is the rehearsal, not a testnet
  note: One host, no credentials. Keyless reads are live data.
dry_run:
  surfaces:
  - operation: x402_free_door (GET /api/free-door)
    cost: '0 USDC — a live 402 route whose accepts[].amount is "0"'
    behaviour: '"Payable and priced at zero — it settles, and charges nothing. It belongs in resources rather than quarantined because it is a live 402 route" (x402.json). Indexed in the x402 Bazaar (PayAI).'
  - operation: any paid door without payment (x402_request_attestation, x402_proof, x402_evidence_bundle, x402_eunomia_data, x402_rwa_evidence, x402_wrapper, x402_art50_marking_evidence, x402_feeds_provider_diff, x402_receipts_batch)
    cost: free
    behaviour: 'HTTP 402 with accepts[] (the only place an amount is published), a server-signed JWS offer, and a csoai.preview / csoai.free_preview block naming what the free path returns.'
  - operation: preview=true (MCP art50_marking_evidence, rwa_evidence, receipts_batch; REST equivalents)
    cost: free
    behaviour: '"true = free unsigned measurement (no card sha, no signature)" / "free unsigned state" / "free: count, span, roots and batch sha256 without the leaves".'
  - operation: omit bundle=1 (x402_proof, x402_evidence_bundle)
    cost: free
    behaviour: 'llms.txt: "Free preview: omit bundle=1 or add preview=1 as the 402 body documents."'
self_test_accounting:
  statement: '"Payments from the operator''s own wallets are recorded as self-tests and never counted as buyers or revenue. Authoritative flag: settled_usdc.excludes_self=true on /api/revenue." (quickstart.json)'
fixtures:
  published_test_values: none — the provider publishes no test cards, test wallets or fixture tokens; do not invent any
