First call in 5 minutes

Get API credentials

Contact the BLOX team to enable API key access for your account (sandbox and production). Register a signer public key with your key.

Authenticate

  • API Key — blox-api-key header (or Authorization: Bearer)
  • Request Signature — RFC 9421 for POST/PUT/PATCH/DELETE

Reads need only the key. See Request Signing when you write.

Machine-readable docs for coding agents and chat tools:

  • /llms.txt — curated index of every page with one-line descriptions
  • /llms-full.txt — full docs concatenated as markdown
  • Per-page raw markdown under /assets/md/, at the page's path with .md appended (e.g. /assets/md/api/getting-started.md), or use Copy as Markdown on any page
