How this service works
Use to check one US statute citation before relying on it. Returns whether the section exists, is in force or repealed, its heading, full text and official source link. 48 states, DC and the US Code. Data: Open US Law v2026.08 (CC BY 4.0). Not legal advice.
Output
Returns a structured response indicating whether the cited section exists in the dataset, whether it is currently in force or has been repealed, the section heading, full statutory text, and a link to the official source. For live-check enabled calls on supported states, also confirms against the official state site.
Example use cases
Verify citation in legal memo
“I've drafted a memo citing Tex. Fam. Code § 6.001 — can you confirm that section exists, is currently in force, and grab its full text so I can double-check I'm citing it correctly?”
Check if a state law was repealed
“Before I rely on RCW 9A.32.030 in my argument, can you look it up and tell me whether it's still active or has been repealed, and what it actually says?”
Validate AI-generated statute reference
“My AI assistant cited Mass. Gen. Laws ch. 93A, § 9 as supporting authority — can you verify that citation is real, in force, and return the actual statutory text and a link to the official source?”
Technical details
Endpoint
GEThttps://x402-tools-production-2755.up.railway.app/tools/statute-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to verify a single US statute citation before relying on it in legal reasoning, briefing, or document generation. Prefer this over general web search when you need structured confirmation (exists/repealed, heading, full text, official URL) rather than a narrative answer. Best for catching hallucinated, outdated, or misquoted statutory references in AI-generated legal content.
Side effects
- Citation not found in the 48-state/DC/US Code dataset (section may not exist or citation format may be unrecognized)
- Ambiguous citation without a named state requires the 'state' parameter to disambiguate
- Live-check unavailable if the official state site is unreachable (no charge in that case)
- Malformed citation string causes parsing failure
- State not yet covered by the dataset returns a coverage error
