description: Operate Helius Wallet API reads through UXC with a curated OpenAPI schema, API-key auth, and read-first guardrails.

Helius Wallet API Skill

Use this skill to run Helius Wallet 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://api.helius.xyz`.
• Access to the curated OpenAPI schema URL:
• `https://raw.githubusercontent.com/holon-run/uxc/main/skills/helius-openapi-skill/references/helius-wallet.openapi.json`
• A Helius API key.

Scope

This skill covers a read-first Helius Wallet API surface:

• wallet identity lookup
• batch identity lookup
• wallet balances
• wallet history
• wallet transfers
• wallet funding source lookup

This skill does **not** cover:

• Helius RPC, DAS, or WebSocket surfaces
• transaction submission
• webhook setup
• the broader Helius platform beyond the selected wallet intelligence endpoints

Authentication

Helius accepts API keys by query parameter or header. This skill standardizes on `X-Api-Key` header auth.

Configure one API-key credential and bind it to `api.helius.xyz`:

uxc auth credential set helius \
  --auth-type api_key \
  --api-key-header X-Api-Key \
  --secret-env HELIUS_API_KEY

uxc auth binding add \
  --id helius \
  --host api.helius.xyz \
  --scheme https \
  --credential helius \
  --priority 100

Validate the active mapping when auth looks wrong:

uxc auth binding match https://api.helius.xyz

Core Workflow

1. Use the fixed link command by default:

• `command -v helius-openapi-cli`
• If missing, create it:

     uxc link helius-openapi-cli https://api.helius.xyz \
       --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/helius-openapi-skill/references/helius-wallet.openapi.json

• `helius-openapi-cli -h`

2. Inspect operation schema first:

• `helius-openapi-cli get:/v1/wallet/{wallet}/identity -h`
• `helius-openapi-cli post:/v1/wallet/batch-identity -h`
• `helius-openapi-cli get:/v1/wallet/{wallet}/balances -h`

3. Prefer narrow validation before broader reads:

• `helius-openapi-cli get:/v1/wallet/{wallet}/identity wallet=HXsKP7wrBWaQ8T2Vtjry3Nj3oUgwYcqq9vrHDM12G664`
• `helius-openapi-cli get:/v1/wallet/{wallet}/funded-by wallet=HXsKP7wrBWaQ8T2Vtjry3Nj3oUgwYcqq9vrHDM12G664`
• `helius-openapi-cli get:/v1/wallet/{wallet}/balances wallet=HXsKP7wrBWaQ8T2Vtjry3Nj3oUgwYcqq9vrHDM12G664 page=1 limit=20 showNative=true`

4. Execute with key/value parameters:

• `helius-openapi-cli post:/v1/wallet/batch-identity addresses:='["HXsKP7wrBWaQ8T2Vtjry3Nj3oUgwYcqq9vrHDM12G664"]'`
• `helius-openapi-cli get:/v1/wallet/{wallet}/history wallet=HXsKP7wrBWaQ8T2Vtjry3Nj3oUgwYcqq9vrHDM12G664 limit=20`
• `helius-openapi-cli get:/v1/wallet/{wallet}/transfers wallet=HXsKP7wrBWaQ8T2Vtjry3Nj3oUgwYcqq9vrHDM12G664 limit=20`
• For `addresses:='[...]'`, keep shell quoting in mind. If your shell mangles that form, pass the JSON array as a bare positional payload instead.

Operation Groups

Wallet Identity

• `get:/v1/wallet/{wallet}/identity`
• `post:/v1/wallet/batch-identity`
• `get:/v1/wallet/{wallet}/funded-by`

Wallet Activity

• `get:/v1/wallet/{wallet}/balances`
• `get:/v1/wallet/{wallet}/history`
• `get:/v1/wallet/{wallet}/transfers`

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. Do not imply RPC write methods, transaction sending, or webhooks.
• Helius labels the Wallet API as beta. Expect response shape drift and keep parsers focused on stable fields.
• Start with small `limit` values before paginating large histories or transfer crawls.
• Identity and funded-by lookups can return 404-style misses for unknown wallets; treat that as a data absence case before assuming auth failure.
• `helius-openapi-cli <operation> ...` is equivalent to `uxc https://api.helius.xyz --schema-url <helius_openapi_schema> <operation> ...`.
