How this service works
HALOWERK x402werk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
Returns a per-receipt reconciliation result indicating whether each receipt was matched to an on-chain transfer (by tx hash, payer address, amount, or timestamp fallback), flags duplicates identified by payment_id, and echoes back the caller's receipt_id for each entry. May also return summary counts of matched, unmatched, and duplicate receipts.
Example use cases
Verify x402 micropayment settlements
“Check whether all the x402 payment receipts my API server issued last hour were actually settled on Base Mainnet — my receiving address is 0xABC...123, look at the last 500 blocks, and I'll give you the list of receipt IDs and amounts.”
Audit weekly USDC income on Arbitrum
“Reconcile all incoming USDC transfers to my address 0xDEF...456 on Arbitrum between unix timestamps 1717200000 and 1717804800 against these 20 receipts from my payment log so I can see which ones confirmed and which are missing.”
Detect duplicate or unmatched payments
“I think some payments to 0x999...fff on Base were counted twice — can you reconcile my receipt list against actual on-chain transfers for blocks 19500000 to 19510000 and flag any duplicates or unmatched entries?”
Technical details
Endpoint
POSThttps://x402.netzhandwerker.de/reconcileWhen to prefer
Choose this endpoint when you need server-side, authoritative reconciliation of EVM-compatible token transfers against a batch of receipts — especially for x402 micropayment workflows where you need to confirm settlements without running your own blockchain indexer. Prefer this over manual on-chain queries when you have multiple receipts with varying match signals (tx hash, payer address, amount, or timestamp) and need a single structured response with per-receipt match status and duplicate detection.
Side effects
- Invalid Ethereum address format (must be 0x + 40 hex chars) returns validation error
- Unsupported chain identifier returns enum mismatch error
- Block range or timestamp window too large may result in timeout or partial results
- Missing required amount_units field on a receipt causes that receipt to be rejected
- Payment not yet confirmed on-chain results in unmatched status (not an error)
- x402 payment authorization failure (insufficient USDC balance) prevents endpoint from executing at all
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| asset | string | Token contract address to reconcile. Defaults to the canonical USDC of that chain. |
| chain | string | Chain as CAIP-2, short name or chain id. |
| window | object | |
| address | string | Your receiving address whose incoming transfers should be read. |
| receipts | array | Your receipts. Each needs at least amount_units; tx_hash makes the match strong, payer and ts make the fallback match possible. |
| time_tolerance_seconds | integer | How far a receipt timestamp may sit from the block time of a payment and still match. Receipt and chain rarely carry the same second. |
