medical.device-udi

FDA GUDID (Global Unique Device Identification Database) lookup — identify a marketed medical device from its UDI or by brand/company. Search by UDI/device identifier, brand name, or company name and get back the device description, version/model number, prescription vs OTC, single-use/kit/combination-product flags, MRI safety, sterilization, commercial-distribution status, publish date, the device identifiers (with issuing agency — GS1/HIBCC/ICCBBA), FDA product codes, and GMDN terms. Free, public-domain US government data. The canonical "what device is this UDI" lookup for supply-chain, clinical, and recall-matching agents; point-in-time public records.

Code samples

cURLbash

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/medical/device-udi?device=xx&company=xx&udi=xxxx&limit=10'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/medical/device-udi?device=xx&company=xx&udi=xxxx&limit=10' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):
#   EVM_PRIVATE_KEY=0x... node --env-file=.env.local \
#     --experimental-strip-types scripts/x402-pay.ts \
#     'https://2s.io/api/medical/device-udi?device=xx&company=xx&udi=xxxx&limit=10'
