` — entity label, sanctions cross-reference, stablecoin-freeze history, and which BA datasets it appears in. ## For AI Agents (MCP server) BlockchainAnalysis exposes its compliance intelligence to AI agents over the Model Context Protocol (MCP). Any MCP-compatible agent can connect to the streamable-HTTP endpoint `https://blockchainanalysis.io/api/mcp` — no API key, no account. Free tools work immediately; paid tools settle per call in USDC on Base via the x402 protocol (the agent's wallet pays, no signup). - [Connect via MCP](https://blockchainanalysis.io/tools/mcp): Setup, claude_desktop_config.json snippet, full tool list and pricing. - [MCP discovery document](https://blockchainanalysis.io/.well-known/mcp.json): Machine-readable server + tool manifest. - Free tools: `check_stablecoin_freeze` (is a wallet blacklisted by Tether/Circle now), `get_freeze_events` (historical freeze/unfreeze/destroy ledger), `check_token_security` (honeypot/rug simulation), `check_token_approvals` (active ERC-20 approvals + risk), `list_supported_chains` (capability discovery). - Paid tools (x402, USDC on Base): `screen_address` ($1.50 — screen a wallet against 1B+ entity labels and multi-list sanctions), `kyt_risk` ($2.00 — KYT risk verdict with sanctions + VASP score), `kyt_tx` ($1.50 — transaction KYT, screens both counterparties of a transfer), `oracle_verdict` ($1.00 — consumer-protection "safe to interact?" verdict), `rwa` ($0.10 — RWA Identity: which real asset a token is and who issues it, with provenance), `label` ($0.10 — Entity Labels: every label on an address with category, threat level and provenance; an unknown address returns an explicit not-found, never an empty result). ## For AI Agents without an MCP client (plain HTTP GET) If you can only open URLs (a browsing tool, a fetch tool, curl), call these directly. They return JSON, need no API key and no account. Anonymous use is capped at 5 calls per day per IP for each tool; over the cap you get HTTP 429 with a Retry-After header. - [OpenAPI spec for these endpoints](https://blockchainanalysis.io/openapi-free.json): parameters, supported chains and response fields. - [Stablecoin freeze check](https://blockchainanalysis.io/api/tools/freeze-check?address=0x12d66f87a04a9e220743712ce6d9bb1b5616b8fc&chain=ETH): `GET /api/tools/freeze-check?address=&chain=`. Is the wallet blacklisted by an issuer right now (`isFrozen`, `issuers`). `previouslyFrozen` is true only when the wallet is NOT frozen now but was in the past; while any issuer still blocks it, it stays false even if other issuers froze and later released it. For the full freeze/unfreeze timeline use the MCP tool `get_freeze_events`. Chains: ETH, BSC, POLYGON, ARBITRUM, OPTIMISM, BASE, AVALANCHE, PLASMA, HYPEREVM, STABLE, INK, BERACHAIN, ROBINHOOD, TRON, SOL. `status: "unverified"` means no issuer contract could be read: treat it as unknown, not as clear. - [Token security scan](https://blockchainanalysis.io/api/tools/token-security?address=0xdac17f958d2ee523a2206206994597c13d831ec7&chain=ETH): `GET /api/tools/token-security?address=&chain=`. Honeypot and transfer-fee-trap simulation plus mint-authority checks. Chains: ETH, BASE, BSC, OPTIMISM, POLYGON, ARBITRUM. - [Token approvals](https://blockchainanalysis.io/api/tools/approval/scan?address=0x12d66f87a04a9e220743712ce6d9bb1b5616b8fc): `GET /api/tools/approval/scan?address=`. Active ERC-20/721 approvals on an Ethereum wallet with a risk tier. - [Safe multisig signers](https://blockchainanalysis.io/api/tools/multisig/by-safe?address=0x849d52316331967b6ff1198e5e32a0eb168d039d&chain=ETH): `GET /api/tools/multisig/by-safe?address=&chain=`. Threshold and signer set; omit `chain` to search all 16 supported chains. - [RWA holder base](https://blockchainanalysis.io/api/tools/rwa-holders?token=0x7712c34205737192402172409a8f7ccef8aa2aec&chain=ETH): `GET /api/tools/rwa-holders?token=&chain=ETH`. Which real-world asset and issuer a token represents, and how many of its holders are sanctioned, mixer-linked or high-risk. - Per-address intel page (HTML, no daily cap): `https://blockchainanalysis.io/a//
`. Entity label, sanctions cross-reference and freeze history in one readable page. Wallet screening against the entity database, KYT and entity labels are paid and not available as plain GET: use MCP (above) or the x402 endpoints in [openapi.json](https://blockchainanalysis.io/openapi.json). ## Documentation & Support - [Documentation](https://blockchainanalysis.io/docs): Product documentation covering compliance, audit, tax, AI features, integrations, API reference, telegram bot, and getting started guides. - [Support Center](https://blockchainanalysis.io/support): Step-by-step how-tos, troubleshooting, billing/account guides, and onboarding workflows. - [Insights](https://blockchainanalysis.io/insights): Long-form articles on MiCA, OFAC sanctions, DAC8, Travel Rule, DeFi compliance, stablecoin regulation, and the state of crypto compliance. - [Changelog](https://blockchainanalysis.io/changelog): Release notes for the platform — new features, regulatory updates, and supported chains. ## Technology - [Technology Overview](https://blockchainanalysis.io/technology): Architecture details — entity database, bloom filter infrastructure, multi-chain analysis engine, and data pipeline. - [Why BlockchainAnalysis.io](https://blockchainanalysis.io/why-blockchainanalysis): Differentiators — proprietary 1.14B+ entity database, jurisdictional regulatory mapping, evidence-grade audit trail, sub-second screening. - [API Documentation](https://blockchainanalysis.io/api-docs): RESTful API for wallet screening, transaction monitoring, risk scoring, and entity lookups.
