x402

Returns a verdict on whether a UK council-tax challenge letter is supportable, blocked pending risk acknowledgment, or not supportable, based on neighbor-band cluster analysis and statutory route eligibility — previewing what the paid $2 letter would contain.

How this service works
Council-tax challenge letter preview — verdict (letter_supportable / blocked-on-risk-ack / not-supportable) from the same neighbor-band cluster + statutory-route engine the $2 letter uses internally, plus exactly what the letter adds. Agent-tier price point for buyers with a $0.25 per-call cap. No LLM.
Output
A structured verdict object containing one of three statuses — letter_supportable, blocked-on-risk-ack, or not-supportable — along with the neighbor-band cluster analysis (comparable properties in the same valuation band area), the applicable statutory route (e.g. VOA informal review or formal appeal), and a preview of exactly what content the full $2 challenge letter would add beyond this check.
Example use cases
Homeowner pre-screening council tax appeal
“I just moved into my house in Bristol and I think I'm in the wrong council tax band — my neighbors seem to be paying less. Can you check if my property at 22 Park Street, Bristol, BS1 5ND in Band E would get a supported verdict for a challenge letter?”
Landlord portfolio council tax audit
“I own a rental property at 8 Victoria Terrace, Leeds, LS6 1DR and it's in Band C. Can you run the council tax challenge check to see if there's a statutory ground to appeal and whether a challenge letter would be supported?”
Buyer due diligence before purchase
“I'm about to exchange on a property at 3 Maple Avenue, Manchester, M20 3LB currently in Band F. Before I commit, can you check if the council tax band looks challengeable based on the neighbor cluster — I want to know the verdict before we complete?”
Technical details
Endpoint
GEThttps://proppulse.theaslangroupllc.com/api/prop/council-tax-checkWhen to prefer
Use this endpoint when you need a fast, deterministic, rule-based assessment of UK council tax challenge viability before committing to the full $2 letter generation. It is ideal for pre-screening large volumes of properties, buyer due diligence pipelines, or letting users understand their options without cost. Prefer this over the full letter endpoint when the verdict is unknown and the user wants a preview first. No LLM inference is involved, so results are consistent and auditable.
Side effects
- Property address not found or unrecognized UK postcode — returns error with no verdict
- Insufficient neighbor-band data in the cluster — may return not-supportable with low confidence
- Property outside England/Wales jurisdiction — statutory routes do not apply, returns blocked status
- Invalid or missing required parameters — returns 400-level error
- Rate limit or payment verification failure — returns 402 or 429
