x402
TLS 1.3 KeyUpdate Record-Layer Epoch Obligation Verifier is a paid API for AI agents from detect.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-11-04).
Validates and computes TLS 1.3 KeyUpdate epoch state: send/receive key generation counters, per-generation record sequence numbers, and mandatory coalesced KeyUpdate response obligations for a given transcript fixture.

How this service works
An offline TLS1.3 record-layer fixture author needs exact independent send/read key-generation and per-generation record-sequence witnesses plus coalesced mandatory KeyUpdate response obligations for an anonymous endpoint transcript.
Output
Returns computed TLS 1.3 KeyUpdate epoch state including independent send and receive key generation counters, per-generation record sequence witnesses, and a determination of coalesced mandatory KeyUpdate response obligations based on the submitted transcript fixture parameters.
Example use cases
Offline TLS fixture state audit
“I have a TLS 1.3 transcript fixture where send_generation is 3, send_sequence is 10, receive_generation is 2, receive_sequence is 7, both finished flags are true, pending_response is false, claim is 100, and no events. Can you compute the epoch obligations and confirm whether a KeyUpdate response is required?”
KeyUpdate response obligation check
“My TLS 1.3 implementation sent a KeyUpdate but I haven't received one back — pending_response is true, send_generation=1, receive_generation=0, send_sequence=4, receive_sequence=0, sent_finished=true, received_finished=false, claim=1, events=[]. Is a mandatory coalesced KeyUpdate response required here?”
Test suite key-generation witness generation
“For my TLS 1.3 record-layer test suite, generate the send and receive key-generation witnesses for this state: send_generation=0, send_sequence=0, receive_generation=0, receive_sequence=0, sent_finished=false, received_finished=false, pending_response=false, claim=0, events=[[1,2],[3,4]].”
Technical details
Endpoint
POSThttps://detect.halowerk.com/v1/F-A-NIGHT-PROTOCOL-TLS-KEYUPDATE/tls13-record-keyupdate-epoch-obligations?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need an authoritative offline computation of TLS 1.3 KeyUpdate epoch state — specifically for test fixture authoring, protocol conformance testing, or debugging TLS 1.3 record-layer key rotation logic without running a live TLS session. Prefer this over manual calculation when you need precise send/receive generation counters, per-generation sequence witnesses, and mandatory response obligation flags validated against the TLS 1.3 spec.
Side effects
- Invalid claim value outside the allowed numeric range causes validation error
- Malformed events array with more than 512 entries or items exceeding limits returns schema error
- Missing required fields (e.g. send_generation, pending_response) causes 400 Bad Request
- Payment not provided or insufficient USDC causes 402 Payment Required
- Internally inconsistent state (e.g. received_finished=true but receive_generation=0) may return a logic error or unexpected result
