want_account_cap_reached

HTTP 429

POST /v1/wants refused a want because this account already holds 10 live wants. A slot frees when a want expires (180 days after it was registered) or is unsubscribed; waiting a day and retrying does not free one by itself. Nothing was stored.

Branch on reason. The title is prose and may be reworded; reason is the stable contract. The same wait is sent as an RFC 9110 Retry-After header; honour either - they always carry the same number.
