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.

Security

Grade A, and why

search-epo 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 8d 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.

Origin

This is a copy

100% identical to search-epo — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Search European patents using the EPO Open Patent Services (OPS) API and Google BigQuery.

Query: $ARGUMENTS

What This Command Does

Provides two complementary European patent search methods:

  1. EPO OPS API - Official EPO database with full-text EP publications, legal status, patent family links
  2. BigQuery (country="EP") - 100M+ worldwide patents filtered for European patents, fast keyword/CPC search

Search Methods

EPO OPS API (Detailed EP Data)

Best for:

  • Full-text EP patent retrieval
  • Legal status and procedural history
  • Patent family linking (INPADOC families)
  • Applicant/inventor search
  • EP publication details (A1, A2, B1, B2)
/search-epo "blockchain authentication"

BigQuery (Fast Broad Search)

Best for:

  • Quick keyword search across EP patents
  • CPC classification browsing
  • Filing trend analysis
  • Cross-jurisdiction comparison (EP vs US vs CN)

Combined Workflow

For comprehensive EP patent research:

  1. Start with BigQuery - Broad keyword search, filter country="EP"
  2. Identify CPC codes - Extract from relevant results
  3. Deep CPC search - BigQuery CPC search for thorough coverage
  4. EPO OPS details - Get full text, legal status, family data
  5. Family analysis - Use family_id to find related filings worldwide

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.
