API reference

Three GET tools: /chains/{registryName} reads chain metadata; /assets/{registryName}?q=ATOM&limit=20&offset=0 searches/paginates asset metadata; /assets/{registryName}/by-denom?denom=uatom selects exactly one case-sensitive base denomination. Example names: cosmoshub, osmosis, juno. Lowercase mainnet registry names only, not exhaustive network discovery. Asset-list limit 1–100 and offset 0–30000. Exact lookup accepts only denom: 1–256 ASCII letters/digits and / : . _ -, starting with a letter/digit. No trimming, additional decoding, symbol/display-unit lookup, pagination or extra filters on the exact route. Missing exact entries return 404 within the cached source; duplicate matches or malformed selected units fail safely. Exact results contain only base denomination, optional name/symbol/display and declared denom units/exponents (0–255, at most 64 unique units). Base unit must have exponent zero and a declared display unit must exist in the unit list. Missing optional source fields remain null, zero exponents stay zero, and integers do not become balances or prices. This bounded subset is not every possible Cosmos asset. No issuer/onchain identity, current network activity, conversion, tradability, funds or safety is verified. Exact projection excludes descriptions, URLs, RPC endpoints, images and private metadata; existing chain/list records remain untrusted source directory data. All three operations are available to agents with Apiary MCP call_free_service after get_service. Source: https://github.com/cosmos/chain-registry, CC BY 4.0. Retain source attribution and licence links; filtered, paginated and exact projections are marked transformed. Source update time is unknown, not retrieval time. No account, credits, subscription, invoice or authenticated provider billing/quota feed applies; admin tracks actual Apiary attempts and configured source caps. GET only; bodies, caller URLs and extra parameters are rejected. All responses include source/licence, fetchedAt and readOnly metadata. Shared cold-fetch protection: 10/minute, 300/day per provider (Apiary limits, not published upstream quotas). Concurrent requests reuse one fetch. Public upstream access has no account billing balance; hosting costs and availability still apply.
