Response

A success is HTTP 200 with the shared envelope: request_id, data (this endpoint's data, see the example) and meta (the charge). An empty result is also 200, with meta.empty true, not charged, and data may be an empty structure or null.

Errors

Errors this endpoint can return
code	HTTP	Billing	Description
`scope_denied`	403	Not charged	This API key lacks the scope the endpoint requires.
`endpoint_unavailable`	503	Not charged	The endpoint is not available right now (no data source connected yet, or no price configured); nothing ran.
`invalid_params`	400	Not charged	The parameters failed validation: a required one is missing, a type or format is wrong, an unknown one was sent, or the POST body is not a JSON object. An error in one parameter starts with its name (`item_id: …`); a missing or unknown parameter starts with `params: …`.
`rate_limited`Retryable	429	Not charged	Over the account's per-minute limit (sliding 60-second window); wait for `Retry-After`.
`too_many_unbilled`Retryable	429	Not charged	In the last 10 minutes at least 50 of your calls to data sources, and over 80% of them, came back empty, not found or rejected; slow down.
`endpoint_busy`Retryable	429	Not charged	The endpoint's per-second capacity across all users is full; retry in 1 second. This does not count toward your per-minute limit.
`insufficient_balance`	402	Not charged	The balance cannot pay for this call (the free quota is used up, or the endpoint does not use it).
`upstream_busy`Retryable	503	Refunded	The data source is busy or cooling down; refunded. Retry after `Retry-After`.
`upstream_timeout`	504	Refunded	The data source timed out; refunded.
`upstream_error`	502 / 503	Refunded	The data source failed; refunded.
`upstream_rejected`	400	Refunded	The data source rejected these parameters (well-formed, but not accepted); refunded.
`not_found`	404	Refunded	The data source has no such item (deleted, or the ID does not exist); refunded.
`reservation_expired`	504	Refunded	The call took too long and was refunded automatically; no data is returned.

Any request can also fail authentication: 401 invalid_api_key, 403 account_disabled, 429 too_many_auth_failures.
