What is ebooksdepository?

A search service for more than 500,000 ebooks and audiobooks, including the independent bookshops that sell indexed titles. It is an index, not a shop, and does not publish prices or handle checkout.

Finding books by title, author, publisher, genre, language, or free-ebook status, then opening the relevant bookshop link. It can also provide aggregate reading data from supported bookshops.

It brings book and bookshop information together without requiring searches across many independent retailers.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00050	$0.00440
Opus 5	$0.00025	$0.00220
Sonnet 5	$0.00010	$0.00088
Haiku 4.5	$0.00005	$0.00044

Security

Grade A, and why

ebooksdepository scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

EbooksDepository

Use EbooksDepository to search ebooks and audiobooks and find indexed independent bookshops that carry a title.

Preferred workflow

Call the anonymous Streamable HTTP MCP server at https://ebooksdepository.com/mcp.
Use search_books for a title, author, or publisher.
Use get_book with the returned slug when full metadata and bookshop links are needed.
Use list_bookshops when the request is about independent bookshops rather than a particular title.
Cite the canonical /es/publications/{slug} page and send the user to a returned bookshop URL.

For direct HTTP, call:

GET https://ebooksdepository.com/api/v1/search?q={query}&lang={code}&limit={1-50}

The endpoint needs no key. Its contract is https://ebooksdepository.com/api/openapi.yaml; documentation is at https://ebooksdepository.com/api.md.

Rules

Never state or estimate a price, convert currencies, or call a store cheapest.
Do not fetch or open checkout_url; present it for the user to open. Opening it can create a cart on the independent bookshop.
EbooksDepository does not process orders or payments; bookshops do.
Attribute reading charts to readers on Publica.la-powered bookshops. They are aggregate reading-time data, not sales or review scores.
Respect standard RateLimit headers and Retry-After on HTTP 429.
The public API and MCP tools are anonymous, read-only, and free.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
