Errors and pagination

Errors#

jsonCopy
{ "error": { "code": "not_found", "message": "Collection not found" } }

HTTP status codes: 400 bad request, 401/403 auth, 404 not found, 409 conflict (for example an order that is no longer fillable), 429 rate limited, 500 server error.

Pagination#

List endpoints accept limit (default 50, max 200) and return a next cursor when more results exist. Pass it back as cursor.

Conventions#

• Timestamps are Unix seconds in UTC.
• Amounts are strings in the smallest unit (wei) with a decimals field where relevant.
• Items are identified by chain, contract (checksummed) and tokenId (decimal string).
• Chains use the slugs listed in Supported chains.
