Convert caller-supplied CSV, TSV, JSON, JSON Lines (NDJSON), or YAML with optional root preservation, deterministic integrity hashes, JSON-encoded nested tabular cells, and explicit rejection of ambiguous duplicate keys or non-finite numbers.

Live health of every supported chain in one call: chain id, block height and how stale the head is. Use it to pick a chain that is actually responding. Via eth_getBlockByNumber.

Latest block height and timestamp of any supported chain, plus how old the chain head is in seconds. Tells an agent whether a node is in sync. Via eth_getBlockByNumber.

ERC20 token balance for any wallet - USDC, USDT, DAI or any token - via balanceOf. Returns the raw amount and the decimals so you can format it. Via eth_call (balanceOf).

Resolve one latitude/longitude pair into bounded, great-circle-distance-ranked nearby GeoNames populated places with country, first-level region, population, timezone, feature code, and source freshness without a request-time network call.
