SEC Blast API

Rate Limits

Every API key has two monthly allowances: a request count and a bandwidth (bytes returned) limit. Both reset at the start of each calendar month, and hitting either one blocks further requests until the reset or an upgrade.

Limits by plan

See pricing for plan details, or contact support@secblast.com for custom limits.

What happens at the limit

Requests over either allowance return 429 Too Many Requests:

JSON
{
  "error": "Monthly request limit exceeded. Upgrade your plan at https://secblastapi.com/pricing"
}

or, when the bandwidth allowance is exhausted:

JSON
{
  "error": "Monthly bandwidth limit exceeded. Upgrade your plan at https://secblastapi.com/pricing"
}

Tracking your usage

The usage dashboard shows requests and bandwidth per key and per day, including an endpoint-level breakdown, so you can see exactly where your allowance goes.
