Four focused endpoints

From product clue to source record.

Build seller onboarding, catalog enrichment, compliance review, and RF research tools with consistent JSON responses. All four endpoints are available on Free and paid plans; Free includes 100 total queries per month.

GET /lookup

Find relevant FCC IDs

Search by brand, manufacturer, model, MPN, product title, or EAN. Review ranked candidates and the evidence connecting them.

Endpoint reference →
GET /validate

Confirm a record exists

Check an exact FCC ID and receive a marketplace screening checklist. Product association and current authorization stay separate from record confirmation.

Endpoint reference →
GET /frequency

Read granted frequencies

Retrieve frequency ranges with units and grant references. Missing values remain unknown.

Endpoint reference →
GET /brand

Follow a brand or grantee

Find matching grantees and their latest FCC IDs. Uses the same shared query allowance as the other endpoints.

Endpoint reference →

Traceable by design

Useful answers.
Clear limits.

Every match links back to FCCID.io and, when barcode evidence is used, Barcode.report. Related news and warnings appear only when their relationship to the FCC ID or exact product is supported.

Search tolerates common label-reading mistakes, including 0/O and 1/I. Corrections are disclosed; validation does not silently replace your identifier.

Start small. Scale when needed.

Simple monthly query limits.

One completed API call uses one query. Internal lookups do not add charges.
