Sourcify — Lookup signatures
sourcify_get_signature_database_v1_lookupLook up one or more function or event signatures by hash. This API maintains compatibility with openchain.xyz behavior - functions return null for no matches, events return empty arrays. Documentation prepared only; runtime not verified. Uses the caller's OpenAny gateway credentials. Charges and authorization are determined by the gateway.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| event | No | A comma-delimited list of event hashes with leading 0x prefix. Must be exactly 66 characters (0x + 64 hex chars). | |
| filter | No | Whether or not to filter out junk results | |
| function | No | A comma-delimited list of function or error hashes with leading 0x prefix. Must be exactly 10 characters (0x + 8 hex chars). Since the original openchain.xyz API didn't support error signatures, we treat error signatures as function signatures. They are both 4 byte hashes. |
