  "body": "ChangeGamer monetizes automated access via HTTP `402 Payment Required`.\n\n- **Index files** (`/llms.txt`, `robots.txt`, `/license.xml`, sitemap), the `getting-started` resource and this pricing page are always free — enforced in code, not just policy.\n- **Premium resources** answer `402` with a JSON body containing the price, a `payment_url` where an access key can be purchased, and retry instructions. Current premium slugs: [Data Formats & Schema](/resources/data-formats), [JSON API for Agents](/resources/json-api), [How ChangeGamer Runs Itself](/resources/autonomous-operations).\n- **`/llms-full.txt`** inlines free resources in full and premium resources as a summary stub only (no premium body content). Full premium bodies require an access key via the individual resource endpoints.\n- Paid requests carry the key as `Authorization: Bearer <key>` (or `x-api-key`).\n\n## License the corpus (for AI teams)\n\nThe highest-value purchase is not a single page — it is the whole curated, fact-checked corpus as **RAG / fine-tuning data with an explicit AI-use grant**. The Corpus and Enterprise tiers below deliver the full `llms-full.txt` (all premium bodies, no stubs) plus the legal right to train on, index, and bulk-use it. Preview the exact machine-ready format for free before buying: `/api/corpus.jsonl` (NDJSON) and `/api/finetune-sample.jsonl` (drop-in supervised-fine-tuning chat format). The €5 starter key is the entry option for a single agent that just needs the premium bodies on demand.\n\n## What you can build with the corpus\n\nThe corpus spans agent frameworks, MCP, RAG, evals, agent security/observability, and x402/payments — curated, cross-vendor reference material, not single-vendor marketing copy. Concrete examples of what a paid license actually lets you do with it (each mapped to the tier whose license grant covers it — see \"Paid tiers\" below for the exact wording):\n\n- **Ground an internal \"ask about agent infrastructure\" support or copilot bot with RAG.** Index `/api/corpus.jsonl` (free preview) or, with a Corpus-tier key, the full `/api/corpus.full.jsonl` as retrieval context — the Corpus license's \"indexing... bulk model-context use\" grant covers this.\n- **Fine-tune, or build few-shot examples for, an agent-building assistant.** The corpus already ships in `/api/finetune-sample.jsonl` supervised-fine-tuning format; the Corpus license's \"AI training\" grant covers using the full corpus this way, not just the free sample.\n- **Keep an LLM's context window current on agent-infra facts instead of relying on stale pretraining data.** Load the full `llms-full.txt` (or call MCP `get_full_corpus`) directly into context at inference time — this is exactly what the Corpus license's \"bulk model-context use\" grant is written for.\n- **Build an internal evaluation or benchmark set for an agent-building assistant** by deriving Q&A or step-by-step test cases from the corpus's existing Q&A and procedural content, for your own training/evaluation pipeline — also covered by the Corpus license's \"AI training\" grant, since this stays internal and derivative rather than redistributing the raw corpus.\n- **Embed corpus content in a commercial product, or distribute a corpus-derived dataset to colleagues across your organization — Enterprise tier only.** The €25 Corpus license's grant stops at internal AI training/indexing/context use; embedding the corpus (or material derived from it) in something you sell, or distributing a derived dataset within your organization, needs the Enterprise license's added \"embedding in commercial products, and distribution of corpus-derived datasets within the licensee's organization\" grant.\n\nNone of the above authorizes public redistribution of the raw corpus or sublicensing it for resale at any tier — see the exact license grants in \"Paid tiers\" below.\n\n## Paid tiers\n\nAll four paid tiers unlock the same premium resource set today (`data-formats`, `json-api`, `autonomous-operations`). Tiers differ in deliverables and license grant, not in gated content.\n\n### Starter key — €5.00 one-time\n\nAn API key that unlocks all current premium resources (`data-formats`, `json-api`, `autonomous-operations`) via `Authorization: Bearer <key>` or `x-api-key` header. Valid until revoked.\n\nBuy at: https://buy.stripe.com/fZu9AMa230eP2b1f0d7EQ00\n\nFulfillment is self-serve and automatic:\n\n1. Pay at https://buy.stripe.com/fZu9AMa230eP2b1f0d7EQ00\n2. Stripe redirects you to https://changegamer.ai/key?session_id={CHECKOUT_SESSION_ID}\n3. That URL returns JSON containing your `cg_` access key.\n\nTiming: key available within seconds of payment. If you get a 404, wait a moment and retry — the webhook may still be in flight.\n\nEmail fallback: reply to your Stripe receipt email if the self-serve flow does not resolve.\n\n### Corpus license — €25.00 one-time\n\nEverything in Starter PLUS:\n\n- A full `llms-full.txt` corpus file delivered by email with all premium resource bodies included (no stubs).\n- An RSL extended AI-use grant: a written declaration permitting AI training, indexing, and bulk model-context use of the full corpus by the named licensee. No public raw-corpus redistribution. No sublicensing for resale.\n\nBuy at: https://buy.stripe.com/fZu28kgqr8Ll2b14lz7EQ01\n\nFulfillment: the same self-serve mechanism as Starter — pay, get redirected to https://changegamer.ai/key?session_id={CHECKOUT_SESSION_ID}, and your `cg_` access key is available immediately. The corpus key unlocks the same premium resource set as Starter; the differentiators are the corpus file and the RSL grant.\n\nThe full corpus file and the RSL extended-use declaration are emailed by the operator to the checkout email address within 1 business day. Keyed buyers do not have to wait for the email: fetch the full corpus immediately at `/api/corpus.full.jsonl` with `Authorization: Bearer <key>` (NDJSON, all premium bodies), or call the MCP `get_full_corpus(api_key)` tool.\n\nEmail fallback: reply to your Stripe receipt email.\n\n### Enterprise license — €150.00 one-time\n\nEverything in Corpus License PLUS commercial redistribution rights:\n\n- The API key unlocking all current premium resources.\n- The full `llms-full.txt` corpus file delivered by email with all premium resource bodies included.\n- An RSL enterprise AI-use grant: AI training, indexing, bulk model-context use, embedding in commercial products, and distribution of corpus-derived datasets within your organization. No public redistribution of the raw corpus. No sublicensing for resale.\n\nBuy at: https://buy.stripe.com/5kQ14ga23d1B6rhbO17EQ02\n\nFulfillment: key delivered self-serve at /key immediately after payment. The corpus file and RSL enterprise-use declaration are emailed within 1 business day; the full corpus is also pullable immediately at `/api/corpus.full.jsonl` (or MCP `get_full_corpus(api_key)`) with your key.\n\n**Invoice-based purchase:** self-serve Stripe invoice payment (pay-by-invoice / net terms) is not yet available for this offer — checkout today is a single upfront Stripe payment. To request an invoice-based purchase instead, open a public issue at https://github.com/beneb89/changegamer/issues describing the invoicing requirement; a team member will follow up. Keep the initial issue high-level — do not paste your company name, VAT number, or contract details into the public issue body; those specifics can be exchanged in a follow-up once off the public tracker. This reuses the repository's regular public issue tracker, not a dedicated sales/procurement inbox, and it carries no support SLA.\n\n### Corpus Updates — annual subscription — €45.00/year\n\nAn always-current corpus subscription:\n\n- The API key unlocking all current premium resources.\n- The full `llms-full.txt` corpus file delivered by email at signup and re-sent at each annual renewal, always reflecting the current premium resource set.\n- An RSL extended AI-use grant valid for the active subscription period: AI training, indexing, and bulk model-context use of the current corpus internally by the named licensee.\n- If you do not renew, you retain rights for the corpus version delivered during your last paid period but are not entitled to future updates.\n\nBuy at: https://buy.stripe.com/eVq14g8XZgdN16X9FT7EQ03\n\nFulfillment: key delivered self-serve at /key immediately after payment. Corpus file and RSL declaration emailed within 1 business day of initial signup and each annual renewal. Annual renewal re-delivery is performed manually by the operator. Renewals mint no new key — the key issued at initial signup remains valid. Between renewals you can always pull the current full corpus at `/api/corpus.full.jsonl` (or MCP `get_full_corpus(api_key)`) with your key.\n\n**Returns and refunds: not permitted once delivered (all tiers).** Every tier here is a digital service delivered immediately on request — the API key is issued self-serve at /key within seconds of payment, and it unlocks the premium bodies and the full corpus pull straight away. There is no return or refund path after that delivery, including for a content-quality complaint. This is what the site declares in its structured data as `MerchantReturnNotPermitted`.\n\n**Why (EU consumers):** You have a statutory 14-day right to withdraw from this contract. Because what you are buying is a digital service delivered immediately on request, you expressly consent to delivery beginning before the withdrawal period expires and acknowledge that your right of withdrawal lapses upon that delivery. Delivery is synchronous for every tier, so in practice that lapse is immediate — which is why the operative policy above is \"not permitted\", not \"14 days\".\n\n**The two narrow exceptions.** (1) *Annual subscription:* you may cancel future renewals at any time via your Stripe customer portal before the next billing date. Cancelling stops future charges; it is not a refund of the current period. (2) *Undelivered emailed deliverables:* the Corpus, Corpus Updates — Annual, and Enterprise tiers also include an emailed corpus file and RSL letter sent within 1 business day. If you bought one of those tiers and that email has not gone out yet, you may still withdraw as to that undelivered part by replying to your Stripe receipt email — note this does not undo the key access already delivered. Adopted Q2 2026; restated 2026-08-05 to lead with the operative no-returns rule.\n\n## How agents pay (machine-readable)\n\nEverything above is available as structured data so an agent can pay without a human:\n\n- Offer catalog (prices, checkout URLs, deliverables, grants): `/api/pricing.json`\n- Payment methods + the exact HTTP 402 retry loop: `/api/payment.json`\n- MCP server `/mcp`: `get_pricing`, `get_payment_info`, `get_resource(slug, api_key)`, `get_full_corpus(api_key)`\n- Gated full-corpus deliverable for keyed buyers: `/api/corpus.full.jsonl`\n- Step-by-step 402 walkthrough: `/resources/paying-for-access-402`\n- Native x402 endpoint (keyless, on-chain USDC): `/api/x402/<slug>` — **not yet enabled** (returns HTTP 503 until on-chain settlement is switched on server-side); poll `/api/payment.json` for live method status. Buyer-side x402 guide: `/resources/agent-wallets-x402`\n\n## Machine-readable licensing\n\nMachine-readable licensing terms are published as RSL at `/license.xml` (linked via the `License:` directive in `robots.txt`): search/discovery is free, AI usage of full resources is licensed per crawl.\n\nThe declared rate: **US$0.05 per crawl** for `ai-all` usage (AI training, inference input, generation) — see `<payment type=\"crawl\">` in `/license.xml`. This is a separate, passive, crawl-level licensing rail declared under Really Simple Licensing (RSL) — it is not an alternative way to buy one of the four EUR keys above and is not the same number space as those Stripe prices, even though the digits happen to coincide today with the unrelated HTTP 402 Bearer-key reference price shown elsewhere on the site. Status: declared, not yet collected — RSL Collective registration is pending (operator action required), so do not assume this fee is being actively charged today. The machine-readable version an agent can fetch or consume programmatically is the `crawl_license` method at `/api/payment.json`, which carries the same rate, currency, and pending-collection status.\n\nCloudflare Pay Per Crawl will be supported additionally once generally available.",
