Execute Nhtsa Vehicle Recall Search V1

by Macaroon Network in Search & web

x402 APIPassing, checked 4 h ago

Look up official U.S. vehicle safety recalls by make, model, and model year -- campaign number, affected component, defect summary, safety consequence, and remedy. The only source used is the National Highway Traffic Safety Administration's own public API (api.nhtsa.gov). Restricted to recall lookup only for v1; NHTSA safety ratings and complaint records are a different part of the same API family and are not covered.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://api.macaroonnetwork.com/execute/nhtsa-vehicle-recall-search-v1' \

  --data-raw '{"input":{"make":"honda","model":"accord","model_year":2020},"predicate":{"conditions":[{"field":"$.results","type":"count_gte","value":1}],"type":"all"}}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://api.macaroonnetwork.com/execute/nhtsa-vehicle-recall-search-v1' \

  --data-raw '{"input":{"make":"honda","model":"accord","model_year":2020},"predicate":{"conditions":[{"field":"$.results","type":"count_gte","value":1}],"type":"all"}}' \
