Tools 15 found in our last check

• subgraphs_scaffold

  Generate a subgraph from observed print events when available; ABI token transfers or public functions only when the contract has never printed. Review the TypeScript, run subgraphs_test until ok: true with written >= 1, read skipped, then subgraphs_deploy. dryRun is DDL only.

• index_ft_transfers

  List decoded SIP-010 fungible-token transfers from Index. Reads are keyless.

• index_nft_transfers

  List decoded SIP-009 non-fungible-token transfers from Index. Reads are keyless.

• index_events

  List decoded chain events from the Index by event type. Use this for event types without a dedicated tool (stx_*, ft_mint/burn, nft_mint/burn, print), and for trait-scoped queries: set `trait` (e.g. sip-010) to match all contracts conforming to a standard — pair with contracts_f…

• index_contract_calls

  List decoded contract calls from the Index (function name, args, result). Set `trait` (e.g. sip-010) to match calls to all contracts conforming to a standard. Note: contract-call cursors are a SEPARATE keyspace from event cursors — they are not interchangeable.

• index_blocks

  List decoded blocks from Index. Reads are keyless.

• index_transactions

  List decoded transactions from Index. Filter by type, sender, or contract. Reads are keyless.

• index_print_schema

  Empirical per-topic print payload schemas for a contract, inferred from sampled on-chain events: each topic's fields with observed Clarity types, decoded TS types, subgraph column types, and presence rates. Use before writing print_event subgraph handlers to learn what's on e.da…

• index_discover

  Discover the Index vocabulary: every event type and its columns, allowed/equality filters, and required-non-null fields (and which types accept `trait`). Read this before building Index queries instead of guessing filters. Anonymous read.

• batch_query

  Run up to 10 public /v1 reads in one round trip (POST /v1/batch). Each item keeps its own auth/quota/pay-per-call semantics; results return in order with per-item status. Paths must start with /v1/index, /v1/subgraphs, /v1/streams, or /v1/contracts.

• streams_tip

  Current canonical chain tip as Streams sees it: block height/hash, burn height, finalized_height, lag_seconds, and the oldest seekable height/cursor for this key's retention window. Call it before a cursor walk to know where the stream ends, and after an ingest to check lag.

• streams_dumps

  List the Streams bulk parquet dumps manifest — coverage range, latest_finalized_cursor, and per-file metadata (block range, row count, size, sha256, signed URL). This is the cold backfill path for downloading all raw data; fetch the file URLs directly (e.g. with DuckDB). Require…

• contracts_find

  Discover deployed Stacks contracts conforming to a trait (e.g. "sip-010", "sip-009", "sip-013"). The discovery endpoint for "which contracts implement X". Reads are public.

• contracts_get_abi

  Fetch a single deployed contract's ABI from the registry (prod-safe). Returns the contract's metadata + full ABI (functions, maps, variables, fungible/non-fungible tokens). Returns not_found if the contract isn't in the registry. Use it to inspect a contract before subgraphs_sca…

• account_whoami

  Show the archive account email at api.secondlayer.tools, not the self-host instance.
