GET /usage

Request

The same call in curl, Node and Python. A path id in the sample is a placeholder.

curl

curl -sS -X GET https://api.agentisend.com/usage \
  -H "Authorization: Bearer $AGENTISEND_API_KEY"

Node

import { AgentiSend } from 'agentisend';

const client = new AgentiSend(process.env.AGENTISEND_API_KEY);
const result = await client.request({
  method: 'GET',
  path: '/usage',
});

Python

import json, os, urllib.request

url = 'https://api.agentisend.com/usage'
headers = {'Authorization': 'Bearer ' + os.environ['AGENTISEND_API_KEY']}
request = urllib.request.Request(url, headers=headers, method='GET')
print(urllib.request.urlopen(request).read().decode())

Tag: usage. Generated from openapi.json; the anchor get-usage is the id the console's error fix links point at.

Errors

The codes this operation can answer with, and what to do about each. Every one arrives with its code, message, fix and docs_url.

• internal_server_error (500, internal_server_error) — Unexpected error. Fix: Retry ONCE after a short pause, with the same Idempotency-Key so the retry cannot double-send. If it fails again, stop retrying and report the x-request-id from the response — that id is what identifies this exact failure in support.
• invalid_api_key (403, invalid_api_key) — API key is invalid or revoked. Fix: Create a new key with POST /api-keys; deleted keys cannot be restored.
• mfa_required (401) — This session has not completed two-factor authentication. Fix: Finish signing in at https://console.agentisend.com/verify with a code from your authenticator app, or one of your recovery codes. Manage the second factor in the console under Settings, Security.
• missing_api_key (401, missing_api_key) — Missing API key in authorization header. Fix: Create an API key at https://console.agentisend.com/api-keys and send "Authorization: Bearer as_...". MCP clients can connect with OAuth instead of a key.
• rate_limit_exceeded (429, rate_ceiling_exceeded, rate_limit_exceeded) — Too many requests. Fix: Back off and retry honoring the Retry-After header.
• restricted_api_key (403, restricted_api_key) — This API key is restricted to sending only. Fix: Use a full_access key (POST /api-keys with permission=full_access) for management endpoints.
