Tools
| Tool | Description | Behaviour |
|---|---|---|
| fetch | Fetch one document or instrument guide returned by search. This is free, read-only content retrieval with no account, credential, payment, or live-price side effects. | Read-only |
| get_market_data_endpoint | Build the exact x402-protected HTTP URL for one live market-data request. Returns method, URL, service notes, pricing docs, and next steps; it is read-only and does not fetch prices, charge a wallet, or submit payment. | Read-only |
| get_pricing_info | Inspect current direct x402 per-call prices, authenticated connector starter-credit costs, supported USDC settlement networks, and the account-plan contact path. This is free read-only metadata; it does not initiate payment. | Read-only |
| get_product_catalog | Inspect Blocksize raw data, supported equity ticker bid/ask, and premium agent-native workflow products, including starter-credit positioning, credit costs, suggested paid prices, endpoint templates, and upgrade path. This is free and read-only. | Read-only |
| get_workflow_endpoint | Build the exact paid HTTP endpoint, method, starter-credit cost, and example body for a premium Blocksize workflow. This is free and read-only; it does not fetch live data, charge credits, or start x402. | Read-only |
| list_instruments | List the supported instruments for one Blocksize service. This is free, read-only catalog metadata; it does not fetch live prices, create accounts, or start x402 payment. | Read-only |
| recommend_account_plan | Recommend a sales-assisted Blocksize account plan from expected live-call volume, team size, recurring use, and SLA needs. This is free and does not collect contact details, create an entitlement, or start a purchase. | Read-only |
| search | Search Blocksize documentation and catalog metadata by keyword. This free read-only search returns document and instrument ids for fetch; it does not return live prices or start payment. | Read-only |
| search_pairs | Discover supported crypto, equity, FX, and metal symbols before using the paid HTTP API. Returns up to 50 catalog matches with asset class, available services, and pricing tier; it is free, read-only, and never returns live prices or starts payment. | Read-only |
