Upsert only; no inferred deletion, fetching or external purchases. Maximum 50 current and 50 previous records, 16 scalar fields, 100000 input bytes. Fixed 0.050000 USDC per batch.
• POST/v1/compare-text$0.004Compare text using deterministic, case-insensitive bag-of-words token-overlap similarity for lexical duplicate screening. Lowercase each input and tokenize with Python Unicode regex \w+ (letters, digits and underscores). Count repeated tokens. Similarity = sum(min(count_a(token),count_b(token))) / max(words_a,words_b,1), rounded to four decimal places. Returns exactly similarity in [0,1], words_a and words_b. Word order and punctuation are ignored; both token-empty inputs score 0, even when equal. Does not measure semantic similarity, Levenshtein edit distance, cosine similarity, or produce a text diff.

• POST/v1/normalize-url$0.004Normalize URL strings for link deduplication and stable hashing without network access. Deterministic URL normalization using Python urllib.parse: strip surrounding whitespace, require parsed http/https scheme and nonempty authority, lowercase scheme and the entire authority (including any userinfo), use / for an empty path, remove the final path-parameter component and fragment. Decode/re-encode query pairs with urllib.parse.parse_qsl/urlencode, preserving order, duplicate keys and blank values; remove keys beginning with utm_, fbclid, gclid or yclid case-insensitively. Does not sort queries, resolve dot segments, remove default ports or validate port numbers/hosts; ports remain in the lowercased authority. Not a fetch, redirect resolver, security validator or universal canonical URL equivalence test. Returns exactly url and sha256 (SHA-256 of its UTF-8 bytes). Non-http(s), missing authority and parser errors return 422. POST application/json with url. Limit: 50000 input Unicode characters per request; for comparison, the lengths of a and b are added.
