Discover deterministic data-quality profiling for 1-5,000 JSON-object rows. Paid execution counts field presence, missing and null values, observed primitive types, primitive cardinality and exact duplicate rows without modifying input; use schema_infer to draft a flat-record contract or tabular_validate to enforce one. This is not statistical inference. This free MCP discovery call does not execute the advertised capability and does not charge; it returns the exact x402 endpoint, price and payment guide for execution.
1-5,000 JSON objects. Rows are analyzed in memory and are not modified.

}Discover a deterministic structural JSON diff between before and after values. Paid execution compares arrays by index and returns up to 1,000 added, removed or changed records with exact JSON paths and before/after evidence; it does not generate JSON Patch. Use json_normalize for stable serialization or json_schema_check for validity.

}Discover deterministic JSON normalization for any JSON value: paid HTTP execution recursively sorts object keys, preserves array order and scalar values, and returns normalized structure plus a deterministic JSON string. Use it for stable comparisons, cache keys and repeatable payloads; use json_diff to identify changes, and never treat this as RFC 8785/JCS canonicalization. This free MCP discovery call does not execute the advertised capability and does not charge; it returns the exact x402 endpoint, price and payment guide for execution.
| Argument | Type | Description |

}Discover recursive JSON Schema checking for objects, arrays and scalars with exact JSON-path errors from ARN's bounded recursive JSON Schema subset. The supplied schema may combine type unions, required/properties, additionalProperties=false, items, enum/const, numeric bounds, string length or safe patterns, array bounds/uniqueness and property-count bounds; unsupported keywords fail closed. Prefer object_contract_check for a new simple top-level contract.

}Discover deterministic top-level JSON field validation for API payloads, automation and AI-agent handoffs. The value must be an object; schema.required finds absent fields, schema.properties.<field>.type finds primitive type mismatches, and additionalProperties=false reports unknown fields. Prefer this for new simple contracts and use json_schema_check for nested or recursive constraints. This free MCP discovery call does not execute the advertised capability and does not charge; it returns the exact x402 endpoint, price and payment guide for execution.

}Discover deterministic comparison of a previous and current execution-evidence snapshot. Paid execution compares candidate identity metadata and all nine functional, security, privacy, copyright, regulatory, transaction-integrity, abuse, regression and economics outcomes; it reports regressions, remediations and whether a fresh verify_execution purchase is warranted. It prevents duplicate verification of unchanged evidence but does not perform or certify the underlying checks.

}Discover deterministic duplicate removal for JSON-record arrays and structured research results. Supply one to eight identity fields: paid execution forms a typed composite key, preserves the first occurrence in original order, and reports exact input, output and duplicate counts; use dataset_profile when you only need duplicate measurement. This free MCP discovery call does not execute the advertised capability and does not charge; it returns the exact x402 endpoint, price and payment guide for execution.
| Argument | Type | Description |

}Rank up to 1,000 caller-supplied providers by quality, success rate, price and latency, returning one selection plus at most three alternates. Candidates marked unhealthy or priced above requirements.maxPrice are excluded; quality defaults to successRate and an empty eligible set returns selected=null with a reason. Use this free read-only calculation only with comparable metrics you already hold because it neither discovers providers nor verifies measurements.
| Argument | Type | Description |

}Discover conservative JSON Schema inference from multiple flat JSON-object records for imports, API contract drafting or validation setup. Paid execution emits stable observed primitive/null type unions and marks a field required only when every row contains a non-null value; nested objects and arrays are rejected instead of guessed. Use dataset_profile for descriptive counts or json_schema_check to validate against an existing schema. This free MCP discovery call does not execute the advertised capability and does not charge; it returns the exact x402 endpoint, price and payment guide for execution.
| Argument | Type | Description |

}Calculate risk-adjusted expected profit, margin and eligibility for one proposed opportunity before execution. Supply revenue, execution cost and any tool costs, fees or failure loss in one consistent monetary unit; omitted tool costs and fees are zero, while omitted failure loss defaults to total costs. Use this free read-only calculation as an economics screen, never as proof of funding, escrow, requirements or buyer legitimacy.
| Argument | Type | Description |

}Discover row-level comparison between two JSON-record tables keyed by one unique field. Paid execution reports added and removed keys plus changed rows with field-level evidence while preserving deterministic order; CSV or spreadsheet rows must be converted to JSON first. Use json_diff for arbitrary nested JSON or tabular_validate to enforce row contracts. This free MCP discovery call does not execute the advertised capability and does not charge; it returns the exact x402 endpoint, price and payment guide for execution.
| Argument | Type | Description |

}Discover deterministic pre-import validation for JSON-record tables, including CSV or spreadsheet rows converted to JSON. Paid execution checks every row for required columns and declared primitive types and returns bounded row-and-field errors; use object_contract_check for one object or json_schema_check for recursive constraints. This free MCP discovery call does not execute the advertised capability and does not charge; it returns the exact x402 endpoint, price and payment guide for execution.
| Argument | Type | Description |
|---|---|---|
| rows* | array | JSON object rows to validate. Between 1 and 5,000 rows. |

}Discover QA-verified translation for up to 2,000 characters on calibrated EN→ES, EN→FR, ES→FR and FR→ES routes. sourceLang defaults to EN, targetLang selects ES or FR, protectedTerms must remain unchanged, and optional context, domain or locale hints guide approved memory and wording; live locale research is excluded. This free MCP discovery call does not execute the advertised capability and does not charge; it returns the exact x402 endpoint, price and payment guide for execution.
| Argument | Type | Description |
|---|---|---|
| text* | string | Source text or Markdown to translate. |
| domain | string | Optional domain label used for approved translation-memory lookup. |
| locale | string | Optional locale hint such as ES-419 or fr-CA. This verified tier does not yet perform live web locale research. |
| context | string | Optional tone/domain context. |
| sourceLang | string | Source language. |
| targetLang* | string | Target language. The source/target pair must be a currently calibrated route. |

Discover deterministic acceptance checking for an automated task or agent execution across nine explicit functional, security, privacy, copyright, regulatory, transaction-integrity, abuse, regression and economics gates. All nine caller-supplied booleans must be true; paid execution returns the candidate id, pass/fail status and failed gate names. Use only after trusted verifiers supply all nine booleans because ARN does not scan code, audit systems or certify compliance. For sustained CI volume, Release Guard offers 2,500 successful checks over 30 days and breaks even with 0.01-USDC pay-per-call at 1,900 checks. This free MCP discovery call does not execute the advertised capability and does not charge; it returns the exact x402 endpoint, price and payment guide for execution.
