How this service works
Look up or list international treaties transmitted to the US Senate for advice and consent via Congress.gov. Pass congress + number (optionally + suffix for partitioned treaties) to fetch a single treaty with parties, topic, transmittal date, and consideration status. Or list by congress. Returns the congress the treaty was received in, the congress that considered it (if any), partial-treaty suffix, topic, transmitted date, and count of parties.
Output
Returns structured treaty data including: the congress that received the treaty, the congress that considered it (if any), the partial-treaty suffix (if applicable), the treaty topic, the transmittal date, a list of parties, and the count of parties. When listing, returns paginated results across all treaties for a given congress.
Example use cases
Example prompt
“Can you pull up the details for treaty number 3 from the 118th Congress, including which parties signed it, what topic it covers, and when it was transmitted to the Senate?”
Technical details
Endpoint
GEThttps://2s.io/api/gov/congress-treatyWhen to prefer
Use this endpoint when you need structured, authoritative data on international treaties submitted to the US Senate — particularly when you need to filter by congress number, look up a specific treaty by number and optional suffix, or enumerate all treaties received by a particular congress. Prefer this over general web search when you need machine-readable treaty metadata including parties, topic, and transmittal dates.
Side effects
- Treaty not found for given congress + number combination returns 404
- Missing required congress parameter may return validation error
- Invalid suffix format returns error
- Rate limiting or payment failure returns 402
- Offset or limit out of bounds returns validation error
