How this service works
Machine-payable x402 offers and books: software pays per request in USDC on Base over HTTP 402, with no account or API key.
Output
Returns a structured 'concept obstruction sheet' containing: total cell count, shared cells, border count, damage score, erasure cost, list of border certificates (each with left/right filing details, change amount, and revision type), largest revisions with relative change percentages, obstruction count, and a unique content-addressed ID for the result. Also includes issuer name and CIK, concept label and units, and the source SEC EDGAR URL.
Example use cases
Audit restatement history for earnings
“Can you check the coherence sheet for Tesla (ticker TSLA) on the XBRL concept NetIncomeLoss under us-gaap? I want to know how many obstructions and revisions exist in their historical SEC filings.”
Validate balance sheet data quality
“Pull the obstruction sheet for the company with CIK 0000320193 on the us-gaap concept Assets — I need to know how many border cells and amendments have been filed and what the erasure cost is.”
Screen for accounting irregularities before investment
“For Microsoft (ticker MSFT), give me the SEC filing coherence analysis for Revenues under us-gaap — specifically how many cells were revised and what the largest relative changes were across their 10-K and 10-Q filings.”
Technical details
Endpoint
GEThttps://market.561.group/v1/issuer-coherence?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, machine-readable analysis of SEC XBRL data coherence — specifically to detect revisions, amendments, and obstructions in a company's financial reporting history for a single concept. Prefer this over raw SEC EDGAR queries when you want pre-computed obstruction scoring and revision certificates rather than raw filing JSON. Ideal for financial due diligence agents, data quality pipelines, or regulatory compliance workflows that need to pay per-query without managing API keys.
Side effects
- Invalid ticker symbol returns an error if not found in SEC's ticker list
- Invalid or non-existent CIK returns a not-found error
- Unknown XBRL concept name (e.g. misspelled tag) returns no data or an error
- Concept not reported by issuer returns empty or minimal records
- Payment not made (HTTP 402) blocks the request without USDC settlement
- Rate limits or SEC EDGAR downtime may cause upstream failures
