Return structured problem+json errors with stable codes, retryability signals, and correlation ids. Use when standardizing API error shapes or making failures debuggable across services.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# API error responses
An error response is an API for failure. Clients branch on it, dashboards
aggregate it, and support debugs with it; design it with the same care as
the success path.
## Method
1. **Adopt problem+json (RFC 9457) as the single shape.**
`{"type": "https://api.example.com/errors/insufficient-funds",
"title": "Insufficient funds", "status": 402, "detail": "...",
"instance": "/orders/123"}` plus your extensions. One shape for every
error from every endpoint, including your gateway and framework
defaults; the client's error handler should never need a second
parser.
2. **Give every error a stable machine code.** `type` (or a `code`
extension: `order_not_found`, `rate_limited`) is the branching key;
`title`/`detail` are prose you may reword freely. Clients matching on
message strings is a contract you created by not providing codes.
3. **Signal retryability explicitly.** 429 and 503 carry Retry-After;
include a boolean extension (`"retryable": true`) so clients need no
status-code folklore. Wrong retryability signals become either give-up
bugs or retry storms (see timeouts-and-retries).

How to install
mdr add amey-thakur/ai-skills/api-error-responses@sha256:3df398a35adc0a3aThe line at the top of this page pins the label git:20260720.1dc980e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
