Check one Base mainnet wallet or contract for ETH and official USDC balances, transaction nonce, and contract-bytecode evidence at a single resolved block.

Get and inspect one historical Base mainnet block by exact number or a latest, safe, or finalized tag, returning its header timestamp, transaction count, gas use, base and blob fees, state and receipt roots, confirmations, and head-distance evidence.

Inspect Base mainnet contract bytecode, common token metadata, and ERC-165, ERC-721, and ERC-1155 interface signals at one resolved block.

Query validated eth_getLogs events from one Base mainnet contract using a required event signature and optional indexed topic filters across a bounded resolved block range.

Estimate gas for one Base mainnet transaction context at a resolved block, add a bounded caller-selected buffer, and preserve RPC rejection evidence without signing or broadcasting.

Read the latest Base mainnet block and a bounded EIP-1559 fee history in one RPC batch, including gas utilization and priority-fee percentile samples.

Inspect Base transaction status and receipt evidence in one call, including success, revert, or pending state, confirmations, actual gas fee, recognized calldata, bounded ERC-20-shaped transfers, and official Base USDC recognition for payment confirmation.

Retrieve newest-first incoming and outgoing Circle USDC Transfer events for one address across a validated, bounded Base mainnet block range.

Resolve 29 common ERC-20, ERC-165, ERC-721, ERC-1155, ERC-2612, and ERC-3009 selectors without a network lookup, or strictly decode arbitrary Ethereum or EVM calldata using a supplied Solidity signature.

Validate EIP-712 typed structured data and derive its domain separator, message hash, and signing digest.

Clean CSV, TSV, JSON, JSON Lines, or YAML records with collision-safe header normalization, deterministic integrity hashes, and exact transformation counts.

Normalize caller-supplied CSV, TSV, JSON, JSON Lines, or YAML to deterministic JSON, infer a Draft 2020-12 schema from that normalized value, and validate one future JSON value in a single x402 call.

Convert caller-supplied CSV, TSV, JSON, JSON Lines (NDJSON), or YAML with optional root preservation, deterministic integrity hashes, JSON-encoded nested tabular cells, and explicit rejection of ambiguous duplicate keys or non-finite numbers.

Get one current weather snapshot for a city/locality name or exact coordinates. Returns the nearest NOAA/NWS station observation where available; otherwise returns the latest MET Norway model point, always labeled explicitly as observation or model with bounded SI fields and source provenance.

Remove duplicate CSV, TSV, JSON, JSON Lines, or YAML records using selected identity fields and report the removed count.

Convert an amount between two supported currencies using one validated ECB daily reference-rate observation. The underlying ECB statistics are available free from the ECB Data Portal; the fee covers bounded retrieval, validation, clearly labelled cross-rate calculation, and x402 delivery.

Repair caller-supplied malformed JSON by safely removing an outer Markdown fence, comments, single-quoted strings, unquoted identifier keys, Python literals, and trailing commas, with transformation hashes and strict rejection of duplicate keys or non-finite numbers.

Resolve one global city or locality name into bounded, population-ranked GeoNames coordinates, country and first-level-region identity, population, timezone, feature code, and source freshness without a request-time network call.

Profile CSV, TSV, JSON, JSON Lines, or YAML records for field types, nulls, uniqueness, and representative samples.

Resolve one latitude/longitude pair into bounded, great-circle-distance-ranked nearby GeoNames populated places with country, first-level region, population, timezone, feature code, and source freshness without a request-time network call.

Create and generate a nested JSON Schema Draft 2020-12 contract by inferring field types and required fields from representative JSON, CSV, TSV, JSON Lines, or YAML records, with equivalent CSV/TSV numeric and null inference, input evidence, and non-enforcing observed bounds.

Validate JSON data against a bounded JSON Schema Draft 2020-12 contract for nested objects, arrays, required properties, types, enums, formats, lengths, patterns, and numeric bounds; return deterministic instance and schema JSON Pointers, explicit error truncation, input hashes, and no remote reference resolution.

Normalize caller-supplied inline Schema.org JSON-LD into deterministic Organization, Product, Service, Article, and Event entities with privacy scrubbing and field-level evidence hashes.

Convert an offset-aware ISO 8601 instant or a local wall time between IANA time zones with explicit DST gap and repeated-hour handling, nearby transition evidence, and a pinned local time-zone database.

Geocode one structural address in the United States, Puerto Rico, or U.S. Island Areas with normalized U.S. Census MAF/TIGER coordinates, optional bounded state/county/tract/block/congressional geography, exact source attribution, and explicit range-interpolation limits.

Get a global weather forecast for a city/locality name or exact coordinates. Returns normalized day/night or hourly periods worldwide: NOAA/NWS is preferred within supported U.S. coverage for optional station conditions and active alerts, while MET Norway provides an attributed open-data fallback globally.

Decode a full 17-character VIN into normalized NHTSA vPIC make, model, year, body, engine, transmission, plant, fuel, and occupancy fields with official source evidence and explicit missing-data semantics.

Bundle six official World Development Indicators into one normalized country snapshot with latest and previous GDP, growth, population, inflation, unemployment, and life-expectancy observations plus source and license evidence.

Compare caller-supplied before and after source snapshots without execution or network access, returning source fingerprints, syntax regressions, structural deltas, function-level changes, and bounded review findings.

Measure caller-supplied source code with Python AST analysis or a deterministic lexical fallback, including per-function complexity, a SHA-256 fingerprint, density ratios, syntax status, and actionable maintainability signals without retaining or forwarding the code. One bounded no-wallet trial is available through the separate HTTP endpoint https://apiacre.com/trials/developer.code-metrics; this MCP tools/call operation remains paid.

Audit exact Python/PyPI, npm, Go, Maven, NuGet, crates.io, or RubyGems dependencies against OSV and return affected packages and vulnerabilities.

Classify software dependency licenses and flag packages that need commercial or legal review.

Validate and audit an OpenAPI document for missing operation IDs, descriptions, responses, and consistency problems.

Generate deterministic, syntax-validated pytest and requests smoke tests from a caller-supplied OpenAPI 3 document, with mutating operations disabled by default.

Detect likely leaked API keys, tokens, private-key headers, JWTs, and credential assignments in caller-supplied source or configuration text. Return type, line, fingerprint, and a fully redacted preview with no network access or code execution.

Statically parse caller-supplied SQL without a database connection or execution, inventory statements and tables, and flag destructive DDL, unfiltered writes, and migration atomicity concerns.

Compare JSON or YAML deterministically and return source hashes plus machine-readable additions, removals, and replacements by path with explicit truncation evidence.
