Developers

Public read-only API and minimal MCP entry points for source-linked SEC 13F context. The public surface is open: no browser account, no public profile flow, and no sales onboarding.

Status

/status

Human-readable deployed SHA, live state and validation boundary.

Public API

/api/openapi.json

Open read-only endpoints for funds, stocks, status, quality and methodology.

Sandbox

/sandbox

Instant limited key: 20 / min, 200 / day.

MCP

/api/mcp

Streamable HTTP public discovery and read-only status/product context.

Tool boundary

Tool	Contract
`get_live_status`	Public dataset state, counts, latest 13F quarter and quality summary.
`get_product_status`	Research readiness, validation boundary and disabled-claim list.
`list_funds`	Public tracked fund list.
`get_trust_artifact`	Machine-readable trust-layer artifact for source-linked workflows.

Public tools are deliberately read-only and keep source, method and quality boundaries visible.

Use policy

13FLOW is a research screen, not investment advice.
13F filings are delayed regulatory disclosures and are not real-time portfolios.
Do not market tool output as validated alpha, expected return or trading recommendation.
