Verifiable random numbers with cryptographic epoch references. Wesolowski 2048-bit VDF epoch chain with on-chain MerkleAnchor reference. For unbiased randomness: POST /v1/rng/commit (free), then GET the reveal_url returned in the response. Do not construct reveal paths yourself.

Verify AI agent outputs against a VEO-2 schema. Checks structural validity, SHA-256 hash integrity (if content hash is present), and optional cryptographic signature on the output (if proof.provider_signature is present). Returns a verdict with per-check details.

Anchor an AI agent decision or audit record to Base mainnet. Submit {schema, payload_hash (SHA-256 hex, 64 chars), metadata}; service queues into a Merkle batch and returns a receipt with pending_anchor status immediately. Full Merkle proof and on-chain anchor_tx available via free GET /v1/notarize/:receipt_id after batch anchors (within batch_threshold receipts or 120s).

Scan text for PII using regex patterns: emails, international phone numbers, national ID numbers, passports, cryptocurrency private keys, credit card numbers, US Social Security Numbers, IPv4 addresses. Always returns sanitized text with PII redacted. Max 50,000 chars. Pattern-based — review for false positives.
