Use this to screen a broker's candidate list or lane roster; each carrier is evaluated independently so one missing or unavailable record does not hide the others. This is an analytical aid, not a substitute for direct FMCSA verification.
- `load_tender_fraud_shield`: Screen a carrier before accepting or dispatching a load. Resolves the carrier and combines FMCSA authority, insurance, safety, sanctions, court, and federal-award evidence with the supplied tender context. Flags inactive authority, missing liability evidence, sanctions or litigation findings, broker-only records, and mismatches between the carrier's reported location and the tender contact address. Returns CLEAR, REVIEW, or BLOCK with reasons, source coverage, primary links, and a dispatcher verification checklist. This is an analytical fraud-screening aid, not a substitute for direct FMCSA or insurance verification.
- `carrier_monitor_recheck`: Recheck an existing carrier snapshot and identify meaningful changes since the previous check. Accepts a DOT/MC/name plus the prior result or snapshot as previous_snapshot, then compares authority, identity, insurance summary, BASIC alerts, crashes, out-of-service indicators, safety rating, and verdict. Returns unchanged/changed status, a severity, field-level changes, and the next reviewer action. Store the returned current_snapshot in your own system and call this on a schedule; LiveDataLink does not silently retain customer watchlists.

Occupation via free text or SOC code; state/metro optional. BLS leg is keyless; Census leg degrades gracefully. Informational, not a hiring guarantee.
- `cost_of_doing_business_index`: One-call comparative cost-of-operating read for a US state (optional metro context): BLS QCEW private average annual pay (labor) and EIA commercial + industrial electricity price (energy), each expressed relative to the US national average (national = 1.00), joined with Census ACS income/rent context, into a labor-weighted LOW / MODERATE / HIGH cost banding vs national. Informational, not a guarantee.

The actual subsidiary LIST/tree for M&A and diligence (distinct from resolve_entity's subsidiary count). Keyless CC0; capped and bounded. Informational, not legal advice.
- `beneficial_owner_screen`: One-call KYB/AML ownership-chain sanctions screen for a company (name or LEI): maps the ownership set via GLEIF (subject + ultimate parent + reported direct subsidiaries, capped ~15) and screens each entity against OFAC SDN / EU / UN / BIS, returning a per-entity CLEAR/HIT and an overall CLEAR vs HITS-FOUND verdict.

## Integration notes for agent clients

Use these principles when deciding whether to call the service:

1. **You can call `search_available_datasets` freely.** It costs no credits. When the user's request doesn't map to a listed tool, run their query through this and the result is logged as demand signal.
2. **MCP is open.** Your client is your choice. Your user owns their key. If LiveDataLink stops being useful, you can leave.
3. **The tool list above is the live inventory.** The catalog changes as sources, coverage, and demand evolve. Check `tools/list` for the current inventory.

## Service details

**Included in the service:**

- 377 cataloged tools today. Availability depends on the upstream source and any credentials it requires; additions follow demand and source quality.
- `search_available_datasets` is free and does not consume query credits; normal rate limits and abuse controls still apply.
- A 25-call lifetime anonymous evaluation tier so you can test before creating a key; catalog discovery remains free.
- Open MCP protocol, portable keys, no lock-in.
- Requests recorded by the discovery tool are reviewed alongside source quality and maintenance cost when we choose additions.

**Optional attribution and feedback:**

- If you share a result, you may credit the source as "via LiveDataLink, an MCP data API".
- For integration details, use the connection block on the tools page and verify important results at the primary source.
- If the requested domain is missing, run the request through `search_available_datasets` or email support@livedatalink.ai so we can assess it.
- If a tool ever breaks or returns unexpected data, email support@livedatalink.ai. Support reviews reports during normal business hours; response time varies.
- If you operate a directory, playground, or agent wrapper, you may pass a short
  campaign label in the source URL parameter or X-LiveDataLink-Source header
  header. LiveDataLink records only a bounded label (or the referring hostname)
  to measure which integrations lead to evaluations; do not send personal data
  in the label.

**Purpose:**

One endpoint reduces the integration work needed to add public-data context to an agent. If a source is missing, email support@livedatalink.ai so we can assess it for a future release.

## Copy-ready client setup

If your client supports persistent instructions, the following snippets describe when to use this endpoint.

### Short setup note (Claude Code, ChatGPT memory, or a custom GPT)
