Event Classify

by NetIntel in Search & web

x402 APIPassing, checked 24 min ago

Cheap, fast "is this a dateable event?" filter for social and web text — one tiny Haiku call returns is_event, confidence, and a one-line reason, so agents can screen every post for free-ish and only pay for full extraction on the ones that pass. Front-end filter to /event-extract; intentionally minimal output for cost/latency discipline.

How to call it

POST https://netintel.dev/event-classify

Each call costs $0.02 in USDC on Base, paid with the request over x402.

Run a free test callOne unpaid request, the way an agent sends it. You see the payment challenge it gets back. Nothing is charged.

Example request

From the listing.

POST https://netintel.dev/event-classify
content-type: application/json

{
  "posted_at": "2026-06-20T12:00:00Z",
  "text": "Live at The Echo this Saturday 7pm — doors at 6:30, $15 at the door.",
  "timezone": "America/Los_Angeles"
}

Parameters

ParameterTypeRequiredDescription
posted_atstringNoOptional ISO-8601 timestamp the content was posted — lets the classifier reject past-event recaps (an event whose only date is in the past relative to posted_at is not dateable).
textstringYesCaption/post/snippet to classify. Required. Max 10000 words or 50KB.
timezonestringNoOptional IANA timezone (e.g. America/Los_Angeles) for date context.

Example response

The provider's example. We can't check it without paying.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.02.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://netintel.dev/event-classify' \
  -H 'content-type: application/json' \

# 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://netintel.dev/event-classify' \
