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). Include Idempotency-Key header to prevent double-charges on retry.

Regex PII scan: emails, US/CA (NANP) phones, dash-formatted national IDs (partial; Taiwan-format alphanumeric IDs not matched), loose passports, 64-hex crypto keys (may flag SHA-256), credit cards (contiguous IIN prefix + spaced/dashed 4-4-4-4 and 4-6-5, Luhn-checked), US SSNs, IPv4. Longest-match overlap resolution. Returns sanitized text. Max 50,000 chars. Expect false positives and misses; non-NANP phones not matched.

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 a SHA-256 payload hash (64 lowercase hex chars) into a Merkle batch on Base mainnet. Payment: $0.001 USDC per submission (batch-settled). Returns anchor_id (202); poll status_url for Merkle proof + on-chain tx hash.
