API
Call api.affix-io.com with a Hub key. The contract is OpenAPI, not a blog post.
OpenAPIIntegrations
Sit beside the stack you already run.
API, Hub, signed webhooks, evidence export, and the public tools.
SDK
Wire from Node with affixio. Prove on the host that holds the record.
affixioWebhooks
Signed pushes when a proof is created, verified, spent, anchored, or a key is revoked.
WebhooksEvidence export
NDJSON or JSON for GRC and log pipelines. Use this when you need a complete record, not only a push.
SIEMAgents
llms.txt and the agent page are the citation surface. Do not scrape a mailbox.
For agentsHub
Register webhook URLs, rotate secrets, issue keys.
Sign InIntegration questions
Do I need two Node packages?
No. Use affixio.
Where do webhook secrets live?
In Hub, per endpoint. Rotate there if one leaks.
Can I poll instead of webhooks?
Yes. Webhooks are for latency. Export is for completeness.
