## Other responses

- `400`: A parameter is missing or invalid. error.code names the problem and error.message says how to fix it.
- `401`: invalid_key: the Authorization header is malformed, or the key is unknown or revoked. A call without the header is never refused with this code, it uses the free tier.
- `403`: dataset_unavailable: the account of the key may not read the data of this country. access_denied: the account is not served. Neither says why. key_required: a call with no key asked for what needs one (a country other than Algeria, an older year of the Journal Officiel, a page of a search past the first). trial_ended: the trial of the account is over.
- `404`: not_found: the code, the issue or the section does not exist. country_not_available: the country is not live, or does not have this dataset yet; the message lists the live countries.
- `429`: rate_limited (more than about 30 requests in 10 seconds from one address), free_quota_exceeded (the free tier of the address is used up for today), quota_exceeded (the daily quota of the key is used up) or monthly_quota_exceeded (the monthly quota of the account is used up, on the plans that have one) or trial_quota (the 1,000 calls of a trial are used up, which does not reset). Retry-After says when to try again.
- `503`: unavailable: a call with a key could not be counted right now. Retry in a moment.
