x402 APIPassing, checked 1 h ago

Keyword web search by Ceramic.ai returns ranked results as structured JSON: a title, URL, & text snippet per result. The discovery entry point for agents & RAG pipelines: search to find relevant pages, then go deeper on any result with the paid /extract endpoints. Pay-per-search. Use ?limit= to cap results (1-10) and ?descriptionLength= to trim each snippet (0 = titles & URLs only) for desired token efficiency. Supports GET & POST

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://minifetch.com/api/v1/x402/search/keyword' \
  -H 'content-type: application/json' \
  --data-raw '{"query":"green tea"}'

# 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://minifetch.com/api/v1/x402/search/keyword' \
  -H 'content-type: application/json' \
  --data-raw '{"query":"green tea"}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
