How this service works
DEA controlled substance schedules (21 CFR 1308.11-1308.15, via eCFR): substance name and DEA Controlled Substances Code Number for schedule I to V table entries matching a name. Substances listed only in paragraphs are not searched. Does not include registration status. Up to 20 matches per call.
Output
A list of up to 20 matching entries (default 10) from the DEA controlled substances schedule tables (21 CFR 1308.11–1308.15), each containing the substance name and its DEA Controlled Substances Code Number and schedule (I through V). Only table-listed entries are returned; paragraph-only entries and registration status are excluded.
Example use cases
Drug scheduling compliance check
“I need to know if buprenorphine is a DEA controlled substance and what schedule it's under — can you look it up and give me the code number?”
Pharmacy regulatory research
“Search the DEA controlled substances table for all entries matching 'amphetamine' and tell me their schedule classifications and code numbers, up to 10 results.”
Legal or policy background check
“Is psilocybin listed as a Schedule I controlled substance under federal DEA regulations? What's its DEA code number?”

Endpoint
GEThttps://api.healthtravel-api.workers.dev/api/health/dea-controlled-substances?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to look up federal DEA scheduling and code numbers for controlled substances by name, directly from the eCFR (21 CFR 1308.11–1308.15) tables. Prefer this over general web search when you need structured, authoritative regulatory data. Not suitable for checking a substance's DEA registration status or for substances only described in CFR paragraphs rather than tables.
Side effects
- Substance name query too short (under 3 characters) or too long (over 60 characters) — returns validation error
- No matches found for the queried substance name — returns empty result set
- Substances listed only in CFR paragraphs (not tables) will not be found even if they exist in the regulation
- Query contains invalid characters (non-letters, non-spaces, non-hyphens) — returns error
- Payment failure via x402 protocol — call not processed
