Method	`POST`
Operation	`post_legal_filings`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Records a filing of one or more of the org's documents with a state or agency, and returns the tracking record.

It is a TRACKING record, not an autonomous filing. With no filing partner wired the honest status is "manual" and the note says so: the documents were generated for signature, and the org files them through its registered agent. Nothing here invents a filing id it does not have.

Every document id must belong to the caller's org; one that does not is a 404 naming it, so a filing can never reach across tenants.

MCP reaches legal through the legal tool, which names its 10 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "list_legal_documents"
         }
       }
     }'
