How this service works
Pay for the outcome. One endpoint for every model, tool and data source an agent needs — each call priced before it runs, at the best value per dollar. 103 models and 100 data and tool APIs.
Output
Returns a structured description of the ClickHouse table schema for on-chain blockchain data, including table names, column names, and data types that can be used to plan SQL queries against the database.
Example use cases
Build dynamic blockchain query builder
“I need to create a tool that auto-generates SQL queries for on-chain data analysis. Can you fetch the ClickHouse schema so I know what tables and columns to work with?”
Audit available blockchain data fields
“Help me explore what blockchain data BlockRun has available—I want to see the full table structure and column types so we can determine what analytics we can actually run.”
Debug failed data pipeline queries
“Our data pipeline is failing because we're querying columns that might not exist. Can you pull the current on-chain ClickHouse schema so I can verify our query matches the actual database structure?”
Technical details
Endpoint
GEThttps://blockrun.ai/api/v1/surf/onchain/schemaWhen to prefer
Use this endpoint when you need to understand the structure of BlockRun's on-chain ClickHouse database before constructing queries — essential for query planning, data pipeline design, or exploring what blockchain data fields are available. Prefer over manual documentation lookups when building dynamic query generation or schema-aware data agents.
Side effects
- Schema unavailable if underlying ClickHouse cluster is unreachable — returns 500 or timeout
- Authentication/payment failure via x402 protocol if USDC balance is insufficient — returns 402
- Rate limiting if too many schema requests are made in quick succession — returns 429
