--- name: bitquery-graphql-skill description: Use Bitquery GraphQL through UXC for onchain trades, transfers, token holder analysis, balances, and market structure queries across supported networks, with OAuth client_credentials authentication and query-first execution. --- # Bitquery GraphQL Skill Use this skill to run Bitquery GraphQL API operations through `uxc`. Reuse the `uxc` skill for discovery, GraphQL execution, OAuth lifecycle, and generic error handling. ## Prerequisites - `uxc` is installed and available in `PATH`. - Network access to `https://streaming.bitquery.io/graphql`. - A Bitquery application `client_id` and `client_secret` are available. ## Authentication Bitquery uses bearer access tokens. The most stable agent path is OAuth `client_credentials`, not a copied temporary token. 1. Create a Bitquery application and note: - application `client_id` - application `client_secret` - token scope `api` 2. Login once with OAuth client credentials: - `uxc auth oauth login bitquery-graphql --endpoint https://streaming.bitquery.io/graphql --flow client_credentials --client-id <client_id> --client-secret <client_secret> --scope api --token-endpoint https://oauth2.bitquery.io/oauth2/token` - This flow completes in one command. No browser approval page is required. 3. Bind the GraphQL endpoint: - `uxc auth binding add --id bitquery-graphql --host streaming.bitquery.io --path-prefix /graphql --scheme https --credential bitquery-graphql --priority 100` 4. Verify auth mapping: - `uxc auth binding match https://streaming.bitquery.io/graphql` - `uxc auth oauth info bitquery-graphql` ## Core Workflow 1. Use fixed link command by default: - `command -v bitquery-graphql-cli` - If missing, create it: `uxc link bitquery-graphql-cli https://streaming.bitquery.io/graphql` - `bitquery-graphql-cli -h` - If command conflict is detected and cannot be safely reused, stop and ask skill maintainers to pick another fixed command name. 2. Discover available root operations: - `bitquery-graphql-cli -h` - Verified roots currently include `query/EVM`, `query/Solana`, `query/Trading`, `query/Tron`, and matching `subscription/*` roots. 3. Inspect a specific operation: - `bitquery-graphql-cli query/EVM -h` - `bitquery-graphql-cli query/Trading -h` 4. Execute with positional JSON and explicit GraphQL selection sets: - `bitquery-graphql-cli query/EVM '{"network":"base","dataset":"combined","_select":"DEXTrades(limit: {count: 1}) { Transaction { Hash } }"}'` 5. Prefer `query/*` operations first. - `uxc subscribe` now auto-negotiates modern `graphql-transport-ws` and legacy `graphql-ws` compatibility profiles for `subscription/*`. - Live Bitquery subscription validation now succeeds when you provide an explicit `_select` that matches a stream-friendly entity shape. - Prefer `subscription/EVM` as the first validation target rather than `subscription/Trading`. ## Capability Map - EVM onchain queries: - `query/EVM` - `subscription/EVM` - Solana onchain queries: - `query/Solana` - `subscription/Solana` - Cross-market / trading queries: - `query/Trading` - `subscription/Trading` - Tron onchain queries: - `query/Tron` - `subscription/Tron` Within those roots, Bitquery exposes entities for tasks such as: - DEX trades - token balances and holder analysis - transfers - blocks and transactions - mempool and realtime activity - market or trading views depending on the root Always inspect the current schema with `-h` and use the narrowest `_select` needed. For subscriptions specifically: - always provide `_select` - start with a high-frequency root such as `subscription/EVM` - prefer direct event shapes before adding `limit` - treat empty selections or query-oriented shapes as likely application-level errors ## Recommended Usage Pattern 1. Inspect root arguments first: - `bitquery-graphql-cli query/EVM -h` 2. Start with a minimal query on one network: - `bitquery-graphql-cli query/EVM '{"network":"eth","dataset":"combined","_select":"DEXTrades(limit: {count: 1}) { Transaction { Hash } }"}'` 3. Add only the fields needed for the task: - buyers / sellers - token addresses - symbols - amounts - timestamps 4. Narrow with GraphQL arguments inside `_select`: - `limit` - `orderBy` - `where` 5. Treat large or realtime queries carefully: - avoid wide selections - prefer one chain / token / wallet at a time on first pass 6. For live subscriptions, start with a known-good high-frequency shape: - `./target/debug/uxc subscribe start https://streaming.bitquery.io/graphql subscription/EVM '{"network":"bsc","mempool":true,"_select":"Transfers { Transaction { Hash From To } Transfer { Amount Type Currency { Name } } }"}' --auth bitquery-graphql --sink file:$HOME/.uxc/subscriptions/bitquery-mempool.ndjson` ## Tested Real Scenario The following authenticated Bitquery flow was verified successfully through `uxc`: - OAuth login with `client_credentials` - auth binding on `https://streaming.bitquery.io/graphql` - GraphQL host help - `query/EVM -h` - authenticated `query/EVM` call on `base` - daemon-backed `subscription/EVM` over WebSocket against live Bitquery infra - repeated live `data` events from a BSC mempool transfer stream The verified query shape was: ```json { "network": "base", "dataset": "combined", "_select": "DEXTrades(limit: {count: 1}) { Block { Time } Transaction { Hash } Trade { Buy { Amount Buyer Currency { Symbol SmartContract } } Sell { Amount Seller Currency { Symbol SmartContract } } } }" } ``` The verified subscription shape was: ```json { "network": "bsc", "mempool": true, "_select": "Transfers { Transaction { Hash From To } Transfer { Amount Type Currency { Name } } }" } ``` ## Guardrails - Keep automation on JSON output envelope; do not rely on `--text`. - Parse stable fields first: `ok`, `kind`, `protocol`, `data`, `error`. - Use `bitquery-graphql-cli` as the default command path. - `bitquery-graphql-cli <operation> ...` is equivalent to `uxc https://streaming.bitquery.io/graphql <operation> ...`. - Prefer positional JSON for GraphQL calls because `_select` is usually required. - Keep `_select` small on first pass and add explicit filters before expanding scope. - Prefer `query/*` for stable agent workflows. `subscription/*` is now validated at runtime, but still depends on provider-specific selection shape. - For subscription validation or automation, start with `subscription/EVM` and an explicit `_select`; do not assume an empty selection or `subscription/Trading` default shape will yield events. - If a subscription opens successfully but immediately returns GraphQL errors, treat that as a query-shape problem before assuming transport failure. - If auth fails: - confirm `uxc auth binding match https://streaming.bitquery.io/graphql` resolves to `bitquery-graphql` - inspect token state with `uxc auth oauth info bitquery-graphql` - manually refresh with `uxc auth oauth refresh bitquery-graphql` - if needed, rerun `uxc auth oauth login ... --flow client_credentials ...` - Do not paste temporary IDE tokens into long-lived skill docs. Prefer application-based `client_credentials`. ## References - Invocation patterns: - `references/usage-patterns.md`
