{"jsonrpc":"2.0","id":1,"method":"tools/list"}crawlgraph_backlinks — Referring domains for a target domain from the Common Crawl webgraph (4.4B edges, 120M domains). Returns linking domains ranked by CrawlGraph authority — useful for SEO audits, competitor backlink profiles, link-building gap research, and verifying who is citing a brand. One call = one quota credit.crawlgraph_gap_analysis — Backlink gap analysis: find domains linking to your competitors but NOT to you. Submit your domain + 1–5 competitor domains and CrawlGraph runs an async job (typically completes in seconds; longer for large profiles). This tool polls up to ~10s and either returns the full gap list, or — if still running — returns the job_id so you can resume via crawlgraph_gap_status. Counts against the gap-analysis quota when the job is submitted.crawlgraph_gap_outreach_targets — The warm-outreach play: gap_analysis filtered to ONLY the linking domains that link to EVERY competitor you listed but not to you. These are the highest-conviction outreach candidates — every competitor in the set has the link, so the topic/audience is verified. Same async pattern as crawlgraph_gap_analysis (polls up to ~10s; returns job_id if still running). Counts as one gap-analysis quota call.crawlgraph_gap_status — Poll a previously-submitted gap analysis job by ID. Use this when crawlgraph_gap_analysis or crawlgraph_gap_outreach_targets returned status=pending with a job_id — call this with the same job_id to retrieve the result once status=completed. Read-only; no quota cost.crawlgraph_releases — List the Common Crawl releases CrawlGraph has indexed (used as release_id in backlinks). Free; not counted against quota.crawlgraph_domain_changes — Quarter-over-quarter diff of referring domains for a domain — what was added or lost between two Common Crawl releases. Useful for catching link rot, sudden spikes (PR coverage), and outreach campaign attribution. Counts as one call against the backlinks quota.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
