ENA Nucleotide Sequence Search (European Nucleotide Archive)

enaportal/ena-search-sequences

Searches the European Nucleotide Archive's public nucleotide sequence records with ENA's query syntax, for example tax_eq(9606) for records of taxon 9606 (Homo sapiens). Each record returns its accession, description and taxon id; up to 100 records per call, with an offset for paging. INSDC sequence records carry no use restrictions. European Nucleotide Archive data as served by Omnial, not an official EMBL-EBI product.

$0.0026 per call

You pay the price shown. If a call turns out to cost more than its quote, you pay the actual price, capped at twice the quote. No monthly minimum. Top-ups start at $5.

Data source

European Nucleotide Archive (EMBL-EBI)

Data from the European Nucleotide Archive (ENA), EMBL-EBI. INSDC sequence records carry no use restrictions (insdc.org/policy). Served by Eden Engine; not an official EMBL-EBI product.

Use it

Five steps: search, inspect, learn, run, settle. No per-tool setup; your agent reaches this tool through the meta-tools it already has.

Connect once and your AI can find and run this tool, and any other it needs.

agent
// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "enaportal/ena-search-sequences" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "enaportal/ena-search-sequences" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "enaportal/ena-search-sequences", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "enaportal/ena-search-sequences", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
