4626.fun auth docs

This page is the named 4626.fun authentication document for the Agent API. There is no public API key. Read endpoints are open. Build and write endpoints require a 4626.fun browser session cookie or a SIWA receipt. Machine-only internals use operator credentials and are not a developer product.

Public reads

GET routes under /api/v1/ for vault reports, explore, lottery, gauges, tokens, and agent profile do not require a header. Optional session or SIWA values are accepted and unused for authorization. Rate-limit headers still apply.

Session and SIWA

SessionA 4626.fun account session cookie from the signed-in site. Used by first-party UI and authenticated agents acting for that account.

SIWASign-In with Agent receipt headers. Required for Agent API build and write routes when no session cookie is present.

401Means the route needs a session or SIWA. Do not retry with a made-up API key.

What 4626.fun does not issue

4626.fun does not sell personal access tokens, OAuth apps, or webhook signing secrets for third-party subscriber products. See 4626.fun webhooks and 4626.fun API docs.
