## Services

- [PrepLayer.ai Content-Addressable Hashing](https://www.zero.xyz/c/preplayer-ai-content-addressable-hashing-2c296d79/llms.txt): $0.002/call via x402. Computes a hex digest hash of input text using sha256, xxhash64, or murmur3, returning the digest, algorithm used, and byte count for caching and deduplication workflows.
- [PrepLayer.ai Multi-Label Text Classifier](https://www.zero.xyz/c/preplayer-ai-multi-label-text-classifier-95eb6c9c/llms.txt): $0.003/call via x402. Applies rule-based multi-label classification to text across a fixed 12-category taxonomy including urgency, spam, crypto mentions, and PII signals
- [PrepLayer.ai Identifier Validator](https://www.zero.xyz/c/preplayer-ai-identifier-validator-f648df3c/llms.txt): $0.002/call via x402. Validates and canonicalizes a single identifier (email, URL, phone, IBAN, payment card, UUID, SHA-256, git SHA, EVM address, or domain) and returns its validity, canonical form, and fingerprint.
- [PrepLayer.ai Entity Extractor](https://www.zero.xyz/c/preplayer-ai-entity-extractor-e6a32c2a/llms.txt): $0.005/call via x402. Extracts structured fields (emails, URLs, IPs, phones, money, ISO dates, UUIDs, EVM addresses, SKUs, semver) with byte offsets and normalized values from unstructured text.
- [PrepLayer.ai Custom Field Extractor](https://www.zero.xyz/c/preplayer-ai-custom-field-extractor-b348dba1/llms.txt): $0.005/call via x402. Extracts caller-defined structured fields from text using regex patterns with deterministic type coercion — no LLM involved.
- [PrepLayer.ai Slugify](https://www.zero.xyz/c/preplayer-ai-slugify-b48ae10f/llms.txt): $0.002/call via x402. Converts arbitrary text into a URL-safe slug with NFKD unicode normalization, configurable separator, and word-boundary-aware truncation.
- [PrepLayer.ai Text Normalizer](https://www.zero.xyz/c/preplayer-ai-text-normalizer-7fe8fa3e/llms.txt): $0.002/call via x402. Deterministically normalizes text via Unicode NFKC, invisible-character stripping, smart-quote/dash folding, whitespace collapse, and case folding, returning a stable content hash for exact equality checks.
- [PrepLayer.ai Batch Endpoint](https://www.zero.xyz/c/preplayer-ai-batch-endpoint-68d92d07/llms.txt): $0.02/call via x402. Execute up to 10 text-processing primitive calls (normalize, validate, extract, redact, classify, dedupe, diff, chunk, slugify, hash, etc.) in a single round-trip request at a 20% discount over individual calls.
- [PrepLayer.ai PII Redaction](https://www.zero.xyz/c/preplayer-ai-pii-redaction-411daadf/llms.txt): $0.005/call via x402. Redacts personally identifiable information (PII) from text, returning sanitized text with byte spans and counts per PII class.
- [PrepLayer.ai Near-Duplicate Document Detection](https://www.zero.xyz/c/preplayer-ai-near-duplicate-document-detection-195e7a3d/llms.txt): $0.01/call via x402. Detects near-duplicate documents in a batch using Jaccard similarity over word 3-shingles and returns a 64-bit SimHash fingerprint per document
- [PrepLayer.ai Text Diff (LCS)](https://www.zero.xyz/c/preplayer-ai-text-diff-lcs-2a4fe3a9/llms.txt): $0.005/call via x402. Computes a line-level LCS diff between two text blobs, returning a structured edit script with insertions, deletions, and unchanged line counts, optionally including a unified-diff string.
- [PrepLayer.ai JSON Schema Validator](https://www.zero.xyz/c/preplayer-ai-json-schema-validator-1874e6e1/llms.txt): $0.003/call via x402. Validates a JSON string against a JSON-Schema subset (type, required, properties, items, minLength, maxLength, pattern, enum, minimum, maximum, additionalProperties) and catches parse errors before they break a pipeline.
- [PrepLayer.ai Text Chunker](https://www.zero.xyz/c/preplayer-ai-text-chunker-09e85bdb/llms.txt): $0.005/call via x402. Splits long text into chunks for RAG retrieval pipelines using sentence-aware, paragraph-aware, or fixed-window strategies.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.
