Reqres Rate Limits

ReqRes enforces per-plan request-rate quotas as of the 2025 relaunch. The /api/* and /app/* surfaces are scoped to an API key (free signup) and metered by daily request count per plan (250/day Free, 1000/day Lite, 100K/day Team). The /agent/v1/* Agent Sandbox is open in v1 with IP-based rate limiting; the paid Agent Developer plan raises the ceiling to 10M requests/month. Exceeding a plan budget returns 429 Too Many Requests. ReqRes has not publicly documented a per-second burst rate or specific retry-after headers; consumers should treat the daily quota as the primary limit and apply exponential backoff with jitter on 429 responses.

Reqres Rate Limits is the machine-readable rate-limit profile for ReqRes on the APIs.io network, in the API Commons Rate Limits shape.

It captures 5 rate-limit definitions, measuring requests_per_day, requests_per_month, and varies.

Limit state is signalled in the retryAfter response header, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 6 backoff/retry policies defined and response codes documented for throttled, quotaExceeded, unauthorized, and forbidden.

Tagged areas include Rate Limiting, Development, Fake API, and Agent Sandbox.

Limits

Free plan — daily requests key
requests_per_day · day
250
The Free plan caps total /api/* and /app/* requests at 250 per day per API key. Exceeding the cap returns 429 until the daily window resets.
Lite plan — daily requests key
requests_per_day · day
1000
$5/month Lite plan raises the daily ceiling to 1000 requests per key.
Team plan — daily requests account
requests_per_day · day
100000
$79/month Team plan provides 100K requests/day shared across the team account, with scoped per-engineer API keys for usage tracking.
Agent Developer — monthly requests key
requests_per_month · month
10000000
$49/month Agent Developer plan provides 10M requests/month against /agent/v1/* with all 15 deliberate failure scenarios unlocked.
Agent Sandbox v1 — open IP rate limit IP
varies
undisclosed per-IP cap on /agent/v1/* without an Agent Developer key
/agent/v1/* is open in v1 and falls back to IP-based rate limiting when no Agent Developer API key is present. The exact per-IP threshold is not published; treat the endpoint as best-effort without a key.

Policies

API key required on /api/* and /app/*
Every request to /api/* and /app/* must include an x-api-key header. Missing or invalid keys return 401. Sign up at app.reqres.in to get a free key.
Session bearer on /app/*
/app/* endpoints additionally require a per-user session bearer token (Authorization: Bearer ) obtained via POST /api/app-users/login. The session bearer carries per-user isolation.
Exponential backoff on 429
On 429 Too Many Requests, back off with exponential delay and jitter and respect the Retry-After header when present. Do not loop tight retries that will compound the quota burn.
Quotas are per UTC day
Daily quotas reset at the start of a new UTC day; plan rollover happens monthly on the billing anniversary.
Deliberate Agent Sandbox failures
The /agent/v1/scenarios surface intentionally returns failure responses (timeouts, malformed payloads, edge-case pagination cursors) so agents can be tested against realistic upstream conditions. These responses are not bugs and should not be retried blindly.
Writes are persisted only on collections/app-users
Legacy /api/users, /api/login, /api/register, /api/logout endpoints simulate success but do not persist. Persistent state lives in /api/collections/* and /api/app-users/* (paid plans add custom schemas and webhooks on data changes).
