Data

Add .json, .tsv or .md to any list or trader page: /index.json · /schema.json · /llms.txt. Defaults match the page; every answer says what applied. Paging: page=2 or offset=50.

Research feed, open: /api/v1/schema.json (snapshots, trade feed ~20–30 s behind, fills, daily list changes).

Bots

Build a copy bot and steer it with these filters: /bots · /bots.md.

Limits

Per IP: 30/min tool calls or uncached reads (burst 20), 20/min heavy (limit=0 or over 50 rows). Over that: 429 with Retry-After.

Rules

Quote rule: past, modelled, not a recommendation or ranking.
