Nodit Web3 Data API Skill#

Use this skill to run Nodit Web3 Data API operations through uxc + OpenAPI.

Reuse the uxc skill for shared execution, auth, and error-handling guidance.

Prerequisites#

• uxc is installed and available in PATH.
• Network access to https://web3.nodit.io.
• Network access to https://raw.githubusercontent.com when using the hosted schema URL directly.
• Access to the curated OpenAPI schema URL:
  • https://raw.githubusercontent.com/holon-run/uxc/main/skills/nodit-openapi-skill/references/nodit-web3.openapi.json
• A Nodit API key.

Scope#

This skill covers a read-first Nodit Web3 Data API surface:

• multichain entity lookup
• native balance lookup
• account transaction history
• token contract metadata lookup
• token price lookup by contracts

This skill does not cover:

• transaction submission
• full JSON-RPC node compatibility
• every Nodit product surface
• broad coverage of chain-specific APIs beyond the selected v1 reads

Authentication#

Nodit uses X-API-KEY header auth.

Configure one API-key credential and bind it to web3.nodit.io:

bash

uxc auth credential set nodit \
  --auth-type api_key \
  --api-key-header X-API-KEY \
  --secret-env NODIT_API_KEY

uxc auth binding add \
  --id nodit \
  --host web3.nodit.io \
  --scheme https \
  --credential nodit \
  --priority 100

Validate the active mapping when auth looks wrong:

bash

uxc auth binding match https://web3.nodit.io

Core Workflow#

1. Use the fixed link command by default:
   • command -v nodit-openapi-cli
   • If missing, create it: uxc link nodit-openapi-cli https://web3.nodit.io --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/nodit-openapi-skill/references/nodit-web3.openapi.json
   • nodit-openapi-cli -h
2. Inspect operation schema first:
   • nodit-openapi-cli post:/v1/multichain/lookupEntities -h
   • nodit-openapi-cli post:/v1/{chain}/{network}/native/getNativeBalanceByAccount -h
   • nodit-openapi-cli post:/v1/{chain}/{network}/token/getTokenPricesByContracts -h
3. Prefer narrow reads before broader crawls:
   • nodit-openapi-cli post:/v1/multichain/lookupEntities input=near
   • nodit-openapi-cli post:/v1/{chain}/{network}/native/getNativeBalanceByAccount chain=ethereum network=mainnet accountAddress=0xd8da6bf26964af9d7eed9e03e53415d37aa96045
   • nodit-openapi-cli post:/v1/{chain}/{network}/token/getTokenContractMetadataByContracts chain=ethereum network=mainnet contractAddresses:='[\"0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48\"]'

If lookupEntities returns HTTP 429 TOO_MANY_REQUESTS, treat it as a plan/tier rate-limit signal rather than an auth failure. Back off and continue with chain-specific reads when you already know the target network.

1. Execute with key/value parameters:
   • nodit-openapi-cli post:/v1/{chain}/{network}/token/getTokenPricesByContracts chain=ethereum network=mainnet contractAddresses:='[\"0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48\"]'
   • nodit-openapi-cli post:/v1/{chain}/{network}/blockchain/getTransactionsByAccount chain=ethereum network=mainnet accountAddress=0xd8da6bf26964af9d7eed9e03e53415d37aa96045 limit=20

Operation Groups#

Discovery#

• post:/v1/multichain/lookupEntities

Account And Token Reads#

• post:/v1/{chain}/{network}/native/getNativeBalanceByAccount
• post:/v1/{chain}/{network}/blockchain/getTransactionsByAccount
• post:/v1/{chain}/{network}/token/getTokenContractMetadataByContracts
• post:/v1/{chain}/{network}/token/getTokenPricesByContracts

Guardrails#

• Keep automation on the JSON output envelope; do not use --text.
• Parse stable fields first: ok, kind, protocol, data, error.
• Treat this v1 skill as read-only.
• Nodit overlaps with Chainbase, Alchemy, and Moralis in some account and token workflows. Prefer Nodit when its multi-chain ergonomics or endpoint shape is a better fit for the task, not by default for every wallet query.
• A concrete good fit is lookupEntities, where Nodit can quickly normalize an input string before you decide which chain-specific follow-up read to call.
• lookupEntities may hit tight plan limits before other reads do. If you get HTTP 429 TOO_MANY_REQUESTS, back off, avoid hot-loop retries, and skip straight to chain-specific reads when the chain is already known.
• Keep contractAddresses lists short in v1 and stay well under the documented per-call maximums.
• For long transaction histories, start with small limit values and paginate deliberately.
• nodit-openapi-cli <operation> ... is equivalent to uxc https://web3.nodit.io --schema-url <nodit_openapi_schema> <operation> ....
