v1.6.0

Added

• Added the cambrian robinhood command group for Robinhood Chain (chain_id=4663).
  Help, completion, docs, OpenCLI, schema discovery, and x402 command routing
  use the same chain registry as the other EVM groups.

Changed

• Refreshed the bundled OpenAPI snapshot from production. Offline metadata now
  includes 20 Robinhood resources. The current schema removes the Clones v3
  pool resources and adds EVM OHLCV resources where the API advertises them.

v1.5.0

Added

• Runtime EVM chain discovery. Any chain id the active OpenAPI advertises is now
  usable immediately as cambrian chain-<id> <resource> (for example
  cambrian chain-10 tokens), so a newly deployed chain works without
  reinstalling or upgrading the CLI. Discovery flows through dispatch, help,
  completion, OpenCLI, docs, and cambrian pay.
• cambrian schema chains now lists runtime-discovered chains (with
  source: "discovered") alongside the curated ones.

Changed

• cambrian schema chains reads the active, refresh-aware registry instead of
  the cached snapshot, so newly deployed chains appear immediately.
• npm run check:chains reports a newly served chain as already reachable via
  chain-<id>, and treats the curated EVM_CHAINS row as the way to add a
  friendly name rather than a hard availability gate.

v1.4.0

Added

• Added the cambrian arbitrum command group for Arbitrum One
  (chain_id=42161). It exposes the 29 operations the EVM OpenAPI advertises
  for Arbitrum across Uniswap/Sushi/Pancake/Clones pools, Aave/Euler/Morpho
  lending, token prices, token lists, DEX discovery, and TVL.
• Added cambrian schema chains, which reports every registered EVM chain and
  the resources the active schema supports for it.
• Added npm run check:chains and src/cli/evm-chain-audit.ts to audit EVM
  chain_id coverage against the live OpenAPI document deterministically.
• Added the add-evm-chain development skill documenting the deterministic
  procedure for adding a future chain.

Changed

• Generalized the EVM layer to a table-driven chain registry (EVM_CHAINS in
  src/cli/evm-chains.ts). Command dispatch, help, shell completion, OpenCLI,
  docs fallback, schema groups, and cambrian pay all derive from it, so
  adding a chain is one table row plus a metadata refresh.
• cambrian pay now offers a group for every advertised EVM chain, including
  ethereum and arbitrum.
• Refreshed the bundled OpenAPI registry. Alongside Arbitrum this also picked up
  two new Ethereum-only lending resources (lending-sky-vaults,
  lending-sparklend-pools) and widened the limit and offset bounds on
  paginated EVM resources.

v1.3.3

Fixed

• cambrian mcp config --client codex now prints valid Codex TOML. Hosted
  configuration uses bearer_token_env_var. Local configuration forwards
  CAMBRIAN_API_KEY with env_vars.
• Updated public examples to use the current Solana price-current
--token-addresses flag.

v1.3.2

Fixed

• Runtime OpenAPI metadata now preserves and validates exclusive numeric
  bounds for parameters and array items.
• Refreshed the bundled offline registry from the current public OpenAPI and
  documentation indexes, including the Solana current-price request shape.

v1.3.1

Changed

• x402 payments now use the current public API paths.
• Updated the packaged skill and public documentation for Ethereum routing.
• Removed obsolete public guidance about internal API paths and compatibility
  details.

v1.3.0

Added

• Added the conditional cambrian ethereum command group. It appears when the
  active EVM OpenAPI schema advertises chain_id=1 on a visible operation.
• Added exact support for OpenAPI numeric enums that contain more than one
  value. The runtime cache now preserves and validates all supported values.

Changed

• Base commands remain fixed to chain_id=8453. Ethereum commands use
  chain_id=1 and include only operations that explicitly support Ethereum.
• Deprecated the evm command. Help, completion, docs lists, suggestions, and
  OpenCLI no longer advertise it. Existing calls still use Base and print a
  warning.
• Kept pay base fixed to Base. This release does not add pay ethereum.
• Updated the packaged agent skill and public documentation for Base and
  Ethereum command selection.

v1.2.0

Added

• OpenCLI self-description now covers every top-level command, nested resource,
  and supported option, including x402, configuration, completions, and MCP.
• cambrian mcp test --mode local now performs a real MCP initialize and
  tools/list exchange and verifies a representative public tool.
• Added cambrian config status for checking API-key configuration without
  printing either environment or stored secrets.

Changed

• EVM and Solana endpoint discovery now prefer their chain-specific OpenAPI
  documents. Either can use the legacy combined Opabinia document when its
  primary is unavailable, then a last-known-good cache or bundled snapshot.
• OpenAPI attempts, validators, caches, and concurrent refreshes are isolated by
  physical source URL while preserving the 15-minute request floor across
  failures, explicit refreshes, processes, and both shared fallback groups.
• --all uses each endpoint's maximum supported page size to minimize requests,
  and help text clarifies that --offline only disables metadata refreshes.
• x402 help discovers and previews gateway pricing at request time instead of
  advertising a hardcoded price.
• Schema controls are documented as advanced commands with explicit cooldown
  behavior, and completion installation warns that shell-file appends are one-time.
• config get-key remains compatible but warns before printing the full secret;
  help recommends safe status checks and warns that set-key can enter shell history.

Fixed

• Commands now reject ignored positional arguments and subcommand-inapplicable
  options instead of appearing to accept them.
• Custom API and hosted MCP URLs must be valid HTTP(S) URLs, and MCP rejects a
  hosted-only --url when local mode would otherwise ignore it.
• Retained compatible deprecated client request types for launch stability,
  removed the unused --discover flag and duplicate contracts, and ensured MCP
  subprocesses receive the caller-injected runtime environment.

v1.1.8

Added

• cambrian docs guides now discovers the guide catalog from the live
  docs.cambrian.org/llms.txt index, and cambrian docs guides <slug> fetches
  any indexed guide without requiring another CLI release.

Changed

• API-key guidance now links to console.cambrian.org and also points users to
  the separate x402 pay-per-call flow.
• Dynamically discovered lending-* Base resources are grouped under Lending
  in command help.

v1.1.7

Fixed

• OpenAPI discovery now enforces a strict 15-minute request floor per physical
  schema URL across normal lookups, explicit refreshes, unknown commands,
  failures, concurrent callers, and separate CLI/MCP processes. Solana and Base
  share one refresh because they use the same gateway document.
• Invalid or empty cache files can no longer hide the bundled command registry,
  and a valid service group from a shared schema remains available if the other
  group is absent.

Added

• Published the validated runtime schema resolver as cambrian/schema so the
  MCP package can share the same cache, cooldown, and fallback behavior.

Changed

• Runtime discovery recognizes the public, unprefixed paths now emitted by
  docs.cambrian.org while retaining compatibility with upstream OpenAPI paths.
