Verifiable random numbers with cryptographic epoch references
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
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.
Regex-based PII scan: emails, US/Canada (NANP) phone numbers, dash-for
Regex-based PII scan: emails, US/Canada (NANP) phone numbers, dash-formatted national IDs (partial coverage; alphanumeric IDs such as Taiwan format are not matched), loose passport patterns, 64-hex crypto private keys (may also flag SHA-256 hashes), credit cards, US SSNs, IPv4 addresses. Always returns sanitized text with PII redacted. Max 50,000 chars. Expect false positives and missed matches.
Anchor an AI agent decision or audit record to Base mainnet
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.
