Parameter-free: the activity snapshot for all 21 tracked blockchains in one call, each with latest weekly transactions, active addresses, fees, value moved and other metrics with 7-day change and analyst reads. Use to compare chains or rank them by activity without 21 separate calls. From public blockchain data, refreshed daily. JSON, no API key. $0.02 per call. Blockchain IQ.

Honeypot check for a Base token: can you sell it after you buy? Simulates a buy and a sell on its Uniswap v2, v3 or v4 or Aerodrome pool and returns sellable, high_tax, honeypot or unknown, both taxes and the pool, plus the owner powers in its code, proxies included (mint, blacklist, pause, fee changes, upgrade), and whether one key holds them. A simulation at one block, not an audit; unknown, never a guess, and no charge if our node fails. Free: GET /v1/token. Trial: /v1/trial.

One chart from a Blockchain IQ crypto analytics dashboard, with the analyst's read of that chart: a time series or ranked table with its unit, source view and refresh time. Pick a dashboard slug and a panel slug, e.g. market-overview/total-market-cap; an unknown panel returns the dashboard's panel list and is not charged. Covers markets, DeFi, stablecoins, derivatives, treasuries and per-chain activity. JSON, no API key. $0.01 per call. Blockchain IQ.

Fetch deployed EVM contract runtime bytecode and its Keccak-256 code hash to fingerprint or compare contracts, or feed a disassembler. Supports Ethereum, Base, Arbitrum, Optimism and Polygon, with optional historical block reads. Returns full hex code, byte size and isContract; an empty-code address returns 0x and a null hash. Key-free RPC with endpoint fallback; code capped at 256 KiB.

Payment receipt and settlement proof for x402 and agent payments, by Liquid Logic X. Input: a Base USDC tx hash (optional memo). Output: JSON proof recorded onchain on Arc mainnet (proofId, from/to/amount, Arc tx, refId) plus a public verify link anyone can check. $0.02 USDC on Base, charged only when a proof is returned. Your paying wallet must be the tx sender or recipient. Liquid Logic X also records proofs on Tempo mainnet. Site: https://liquidlogicx.com

Identify what an EVM address IS in one keyless call: contract/protocol identity (entity, name, category) from Open Labels Initiative attestations with trusted-attester consensus, plus on-chain truth (is_contract, code_hash), reverse ENS/Basename, sanctions (OFAC/UK/EU/UN) and scam-drainer flags. Cited provenance; unknown addresses answer with empty labels, never a 404.

Compare two lockfiles and report what a manifest diff cannot see. Reports newly installed transitive packages, resolved version moves with breaking risk, a registry that changed, and the most serious finding available here: the same version with a different integrity hash, meaning the artifact behind a version that was supposed to be immutable is not the one that was there before.

Audit a CI workflow for what it leaves movable or undeclared. Reports actions pinned to a tag rather than a commit - a tag can be moved by whoever owns the action, so the code a step runs can change without this file changing - missing permissions and timeouts, a job depending on one that is not declared, a pull_request_target trigger, and an expression interpolated straight into a shell command.

Audit telemetry attributes against a contract, and against the thing a schema cannot see: cardinality. Reports missing required attributes, undeclared attributes, an attribute appearing as two types across the batch, and an attribute whose distinct values exceed your limit - because in a metrics backend each distinct value is a separate series, and that is how an index or a bill explodes.

Audit a real response against what the OpenAPI document promises for that operation. Resolves the declared status exactly, by range such as 2XX, or through default, checks declared response headers are present, and validates the body against the declared schema for its media type. Catches an implementation that has drifted from its own published contract.

Audit a real request against the OpenAPI document it should satisfy. Matches the operation the way a router would, checks every path, query and header parameter against its declared schema, validates the body against the declared media type, and reports whether the credential the declared security scheme expects is present. You supply the request, so this works against an API nothing external can reach.

Audit your own delimited data against a contract you declare, and get one pass/fail plus the exact row and clause of every breach. Checks types, required values, enums, numeric bounds, lengths, patterns, uniqueness, composite primary keys, null-rate ceilings, header drift and encoding damage in one pass. A pass means the audit was complete and nothing broke, so a file beyond the bounds reports incomplete rather than passing. Nothing is fetched: you supply the rows.

List of analyst-curated crypto sector indices and thematic baskets, each with slug, name, description and number of member coins. Use to find which coins belong to a crypto sector or narrative, then fetch one index for its members and prices. JSON, no API key. $0.02 per call. Blockchain IQ.

A registry of token records with a build log.

One $0.02 x402 write in USDC on Base, Polygon, Solana or Arc; reads, pages, log and OpenAPI are free.
