Copy this guide into your AI agent. It links to the current REST API and MCP documentation.

You are helping someone integrate their system with Levr. Use Levr's published documentation and machine-readable contracts as the source of truth. Do not invent endpoints, fields, or MCP tools.

  1. Start with the Levr API documentation to choose between a server-to-server REST integration and a user-authorized MCP connection.
  2. For REST, read the Markdown REST API guide, choose the user’s task, then fetch only the relevant resource guide and operation Markdown. Resource indexes include task guidance. For funding recommendations, start with the Matchmaking guide. Use the OpenAPI specification for exact paths, authentication, parameters, and envelope schemas.
  3. For REST client intake, Deal applications, or project Criteria, fetch that resource's contract_url. Its Application Contract is the authority for the current questions, stable keys, repeatable groups, file-transfer steps, accepted answer shapes, conditional visibility, supported operation URLs, and integration instructions. Repeatable fields require the returned item_id. File bytes use the expiring upload_url and multipart field named file; they never belong in JSON. Do not substitute a static example or the latest application definition.
  4. For an AI client acting with a signed-in user's access, read the MCP connection instructions in Markdown first, then the Model Context Protocol guide if needed. Let the connected MCP server expose its current tools and input contracts; do not infer tools from the REST API. Read the relevant MCP resource guide and follow the discovered tool’s revision, file-transfer, and confirmation requirements.
  5. Use URLs from the record handoff when supplied; otherwise use this documentation environment. Keep API keys and file-transfer credentials out of browser code, logs, prompts, and source control.
  6. Before implementing a write, verify authentication, required inputs, idempotency, error responses, and retry guidance in the current contract. If an operation is not documented, do not assume it exists.

Prepare a Deal Application answer file upload

Read as Markdown · All MCP tools

deal_applications.prepare_answer_file_upload

Prepare a five-minute upload to a file question in a Deal Application; preparation attaches nothing. Read contract/answers first. POST multipart field file to the returned URL with transfer_token as Bearer credential; no separate API key. Read the HTTP receipt, then list files to verify. Retry the same bytes at the returned URL while its credential is valid. After completion, do not prepare the upload again with the old answers revision. Use a new idempotency_key for a new upload. Keep tokens/bytes private. Limit: 25 MiB per file; room limits and current permissions apply.

Availability depends on your assigned tools. Scopes do not grant record access. Read the tool description and current resource before changing it; follow the required revision and idempotency fields below.
