x402 APIPassing, checked 5 h ago

Run 2-5 web searches in one call with a 20% volume discount vs. individual searches. Each query returns ranked results (title, URL, snippet). Ideal for multi-faceted research or comparing sources on different aspects of a topic. If some queries fail upstream, the call returns the ones that succeeded with an error on each failed query and is charged; a call where every query fails is not charged.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.08.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://agent402.tools/api/multi-search' \
  -H 'content-type: application/json' \
  --data-raw '{"queries":["x402 payment protocol","USDC micropayments"]}'

# 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://agent402.tools/api/multi-search' \
  -H 'content-type: application/json' \
  --data-raw '{"queries":["x402 payment protocol","USDC micropayments"]}' \
