How this service works
The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.
Output
Returns a JSON object with ok:true, a meta block echoing the query parameters, an items array of matching opinion records (with arbitrary fields), a nullable total count of matching rows, and a source object identifying the upstream provider, URL, and license.
Example use cases
Example prompt
“Can you pull up the court opinion for citation '410 U.S. 113' — I need the full opinion record including the source and license info.”
Technical details
Endpoint
POSThttps://2s.io/api/law/opinionWhen to prefer
Use this endpoint when you need to retrieve a specific court opinion by its citation string (e.g. '410 U.S. 113') or a known numeric opinion ID, and want a pay-per-call approach with no API key or subscription. Prefer this over subscription legal databases when cost-per-call is preferable to monthly fees, or when integrating into an agent pipeline that needs on-demand legal lookups.
Side effects
- No matching opinion found returns empty items array with total null or 0
- Invalid citation format or missing both citation and opinionId may result in error or empty result
- opinionId of 0 is excluded (exclusiveMinimum:true), submitting 0 may cause validation error
- Upstream legal data provider unavailable returns non-ok response
- Payment failure via x402 blocks request before reaching the API
