# Ravn

> Verified B2B contact and company data for AI agents: validate emails, find work emails from a name and company, read company websites, look up phones and IPs, and search licensed people and company records. REST API, remote MCP server and CLI with the same tools.

## Getting started

1. A person creates the account: an agent can't receive the sign-in code itself. Ask your human to run `npx ravn login` (or sign up at https://askravn.com/#start) and give you the key, or to set RAVN_API_KEY.
2. Pick a path:
   - MCP with OAuth (Claude, Claude Desktop, Claude Code, Cursor): add the server URL `https://api.askravn.com/mcp`; the client opens Ravn's sign-in page (email code → Allow). No key needed. With a key instead: `claude mcp add --transport http ravn https://api.askravn.com/mcp --scope user --header "Authorization: Bearer $RAVN_API_KEY"`
   - CLI (terminal agents, CSVs, scripts): `npx ravn <tool> --field value`; install the Claude skill with `npx ravn skill install`.
   - REST: `POST https://api.askravn.com/v1/tools/{tool}` with `Authorization: Bearer rw_live_…` and a JSON body.
3. Confirm the connection: call `get_account` (free). It returns the plan, your connected provider keys, lookups used this billing period and your monthly spending cap.

## Pricing

- Free: 1,000 lookups to try (lifetime).
- Ravn: $24/month, includes 10,000 lookups a month. Beyond that, $1 per 1,000 lookups ($0.001 each), billed monthly. Misses are free.
- Set a monthly spending cap any time (default cap: $100 of usage beyond the plan; `ravn cap <dollars>` or PUT /v1/billing/cap; $0 stops at 10,000). At the cap the API returns 429 `spend_cap_reached`.
- People and carrier tools run on your own provider key.

## Rules for agents

- Branch on `status`: "ok" (results present) or "not_found" (normal, nothing charged). Errors are HTTP 4xx/5xx with `{"error": {"code", "message"}}`; branch on `error.code`.
- People and carrier tools need your own provider key: on 403 `provider_key_required`, your human runs `ravn keys add pdl` (or twilio). On 429 `spend_cap_reached`, your human raises the cap (`ravn cap <dollars>`); on other 429s, wait `Retry-After`.
- For CSVs, run `enrich --dry-run` first, then `--limit 10`, then the full file.
- Run `validate_emails` before sending to any list and drop invalid and risky addresses. Never contact people who opted out, and never use the data for credit, employment, insurance or housing decisions.
