summary: >-
  LI.FI deliberately does NOT provide a conventional test-mode sandbox for its
  core routing API. Because bridges and DEXs have limited testnet support and
  almost no testnet liquidity, LI.FI retired testnet support and advises running
  test transactions on mainnet with small amounts on low-gas L2s. There are no
  test API-key prefixes, no magic test token addresses and no test clocks. A
  staging host and an Intents testnet stack do exist and are recorded below.
test_mode:
  available: false
  key_prefixes: null
  note: >-
    There is no test-vs-live key separation. The same x-lifi-api-key works
    against production and staging.
official_guidance:
  policy: Run test transactions on mainnets.
  rationale: >-
    Bridges and exchanges have limited support for testnets and there is almost
    no liquidity on those networks.
  cost_advice: >-
    Test on chains with low gas fees. Optimism and other L2 chains are
    recommended as cost-effective choices.

  note: >-
    https://docs.li.fi/llms.txt lists these testnets as available chains, while
    https://docs.li.fi/sdk/testing-integration states testnets are no longer
    supported for integration testing. Both statements captured verbatim; treat
    mainnet testing as the current official guidance.
test_values:
  test_cards: null

  test_clocks: null
  fixtures: null
  note: >-
    No magic test values are published. The token addresses documented at
    https://docs.li.fi/mcp-server/tools are real mainnet contract addresses for
    convenience, not test fixtures.
dry_run_surface:
  description: >-
    The read-only endpoints are the practical dry-run surface: a quote can be
    requested and inspected without ever signing, since the API only returns an
    unsigned transactionRequest.
