  • fresh402_check

    Check whether public HTML, JSON or text changed; optional html_attributes on a new URL watch detects same-text link and selected attribute changes without altering older watches; use for on-demand freshness checks and a compact deterministic text diff, not background monitoring. Supply exactly one of url or watch_id. A URL-based paid Check can create a watch; an ID reuses its saved URL/rules, so omit all content-rule fields. Reuse returned watch_id/hash for later checks; first URL check without prior state reports changed:null. Optional cache reuse still costs $0.005 USDC per call on Base main…

  • fresh402_extract

    Extract readable text, metadata, headings, public links and embedded JSON-LD from one public HTTPS document. Use to read static HTML, JSON or plain text; no watch or prior registration is needed. Optional CSS scope, noise exclusions and exact JSON Pointer selection via json_pointer, or an ordered projection of up to8 fields via json_pointers (mutually exclusive; JSON only, any missing field returns422). One fetch/JSON parse with aggregate work/output limits. Omit json_pointer to retain full-document extraction. max_chars defaults to 20000 and limits returned text, not fetch size. Does not rend…

  • fresh402_openapi_contract_diff

    Detect bounded directional compatibility evidence in a public JSON OpenAPI3.0/3.1 contract: paths/methods, required fields, supported scalar type/enum/null domains, and effective authentication alternatives/scopes. Request acceptance and response guarantees have opposite compatibility directions. Complex schema composition, custom dialects, ambiguous visibility and unexpanded references remain review/unknown; no general satisfiability or compatibility proof. Use for API contract review; Smart Diff is for general documents. First register the contract URL with free fresh402_register, without se…

  • fresh402_register

    Create or retrieve a free persistent baseline for public HTTPS HTML, JSON or plain text. Use before Smart Diff or OpenAPI Contract Diff, or to obtain a reusable watch_id/hash for Check. Required url plus optional CSS/JSON exclusions and opt-in html_attributes identify the watch; changing rules creates a different watch. Repeating the same registration returns existing state without fetching or refreshing it. Reuse the actual returned watch_id; never invent an ID. Registration is free ($0), subject to quotas, and requires no x402 payment client; subsequent comparison tools are paid. Check also …

  • fresh402_smart_diff

    Explain structured changes in a registered public document: JSON Pointer changes, HTML block changes and deterministic significance hints. Use instead of Check when a changed/unchanged flag or short text diff is insufficient. First obtain watch_id with free fresh402_register; saved URL/rules are reused. compare_to is previous (default) or baseline; previous_hash overrides it when the same-watch snapshot is retained. Up to200 content changes; explicit json_array_keys match unique typed item identities and report moves separately, with pure reorder unchanged and source hashes still order-sensiti…
