An accession number is the unique identifier EDGAR assigns to each individual submission — formatted like 0001193125-24-000123 — letting you cite and retrieve one exact filing.
While the CIK identifies the filer, the accession number identifies a single submission. Together they uniquely address any document in EDGAR. The format encodes the filing agent's CIK, the two-digit year, and a sequence number.
For provenance, the accession number is the atomic citation: it pins a datapoint to the precise filing it came from, so a claim can be re-verified at the source forever.
Accession 0001193125-24-000123 points to one specific filing — paste it into EDGAR and you get that exact document.
Arkolith attaches the accession number to derived datapoints, so every figure links back to the one SEC filing that produced it — anti-hallucination grounding by construction.
Arkolith turns this into live, sourced data your agent can query — SEC filings, insider activity, and market data behind one key, every datapoint traceable to its origin.
