tools
check_access
Verify an access key and report what it unlocks. Returns valid:true/false; when valid, the tier, when it was created, the premium slugs it unlocks, and that it grants the gated /api/corpus.full.jsonl + get_full_corpus deliverable. Never returns the key, email, or Stripe session. Use this to confirm a freshly-purchased key works before relying on it.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['api_key'], 'properties': {'api_key': {'type': 'string', 'description': 'Access key to verify (cg_...)'}}, 'additionalProperties': False}
get_access_info
Return current access and pricing information for ChangeGamer resources.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
get_article
Fetch one ChangeGamer guide (editorial article) by slug as full Markdown with its metadata header. Always free — never part of the paid corpus. Use list_articles to discover slugs.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['slug'], 'properties': {'slug': {'type': 'string', 'description': 'Article slug (e.g. "rag-in-production")'}}, 'additionalProperties': False}
get_cluster
Fetch one ChangeGamer guide cluster (topic bundle) from the free editorial layer: pillar metadata, every sub-article with variant URLs, and the pillar’s full Markdown body. Use list_articles to discover cluster ids.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['cluster_id'], 'properties': {'cluster_id': {'type': 'string', 'description': 'Cluster id, e.g. "rag-in-production"'}}, 'additionalProperties': False}
get_corpus
Return the entire free corpus as one document (every free resource title, description, canonical URL, and full Markdown body) — the same content as /llms-full.txt. Premium resources appear as a stub with a purchase link, not their body. Use this to ingest everything in a single call; the response is large.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
get_full_corpus
Return the ENTIRE corpus including premium resource bodies in one document — the keyed deliverable of the Corpus/Enterprise license. Requires a Corpus- or Enterprise-tier api_key (a Starter key unlocks premium resources but NOT the corpus file); without an entitled key a payment-required/upgrade object is returned. The free, premium-stubbed version is get_corpus.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'api_key': {'type': 'string', 'description': 'Corpus/Enterprise license key (cg_...)'}}, 'additionalProperties': False}
get_payment_info
Return the agent payment manifest: every way to pay (HTTP 402 + Bearer key, MCP, Stripe checkout, x402, RSL per-crawl), the exact 402 retry loop, what is always free, and the recommended path per use case. Same data as /api/payment.json.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
get_pricing
Return the full paid-offer catalog: every tier with price, currency, interval, checkout URL, what it unlocks, deliverables, and license grant — plus the free layer and premium slug list. Same data as /api/pricing.json.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
get_resource
Fetch a ChangeGamer resource by slug. Free resources return full metadata and Markdown body. Premium resources require a valid api_key; without one a payment-required object is returned.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['slug'], 'properties': {'slug': {'type': 'string', 'description': 'Resource slug (e.g. "getting-started")'}, 'api_key': {'type': 'string', 'description': 'Access key for premium resources'}}, 'additionalProperties': False}
get_stats
Return corpus stats: total/free/premium counts, per-category counts, tag count, newest/oldest update dates, the 10 most recently updated resources, feed URLs — plus an editorial block (guide count, words, newest publish) merged at runtime from the static articles index. A small freshness/size signal to poll before deciding whether to re-ingest.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
list_articles
List all ChangeGamer editorial guides (always free, separate from the licensable corpus): cluster-first hub/spoke graph with every article's title, search intent, word count, takeaways count and variant URLs. No body content — fetch bodies with get_article.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
list_resources
List all ChangeGamer resources with metadata and absolute URLs. Returns slug, title, description, category, tags, updated date, premium flag, and HTML/Markdown/JSON variant URLs. No body content.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
search
Keyword search across ALL ChangeGamer content (resources and editorial guides) with server-side ranking: term hits in title weigh most, then tags, then description. Returns ranked rows with type, slug, title and .md URL (no body content). Use get_resource/get_article to fetch winners.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['q'], 'properties': {'q': {'type': 'string', 'description': 'Search query — one or more keywords'}, 'limit': {'type': 'integer', 'maximum': 25, 'minimum': 1, 'description': 'Max results (default 10)'}}, 'additionalProperties': False}
search_resources
Search the ChangeGamer corpus by keyword. Ranks resources by relevance across title, description, tags, category, and body, and returns metadata plus HTML/Markdown/JSON URLs (no body content). Use this to find resources before fetching them with get_resource.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['query'], 'properties': {'limit': {'type': 'integer', 'maximum': 50, 'minimum': 1, 'description': 'Maximum number of results (default 10).'}, 'query': {'type': 'string', 'description': 'Search keywords, e.g. "retrieval augmented generation" or "mcp auth"'}}, 'additionalProperties': False}
