Φ RESEARCH SYSTEMS · x402 FAILURE LAB

Find the failure before the payment becomes ambiguous.

One bounded, read-only recon of one x402 payment path — from HTTP 402 and PaymentRequired through signing, verify, settle, response, receipt, and recovery.

SYSTEM → EVIDENCE → REPAIR

01 · OBJECT

x402 Integration Readiness / Failure-Surface Recon — USD 300

One payment path. One bounded falsification pass. No production mutation.

The scope is fixed before work begins. If the system cannot fit one bounded recon object, BHRIGU narrows or declines it before agreement.

02 · DELIVERABLE

You receive four x402-specific objects

Payment-state map

HTTP 402, PaymentRequired, payer signing, verify, settle, response, receipt/evidence, and recovery boundaries.

3 highest-impact failure findings

Focused on ambiguity, duplicate execution, stale authority, paid-without-delivery, and observability gaps that are actually supported by evidence.

Evidence for each finding

Public code/docs, observable behavior, state transitions, hashes/receipts where available, and reproducible evidence without requesting secrets.

Exact verification / repair blueprint

The invariant to enforce, the checkpoint or boundary to change, and the acceptance test that proves closure.

03 · FIT

Good fit for teams building or shipping x402

Paid AI / agent APIs
MCP tools with machine payments
x402 facilitators
Base / USDC payment paths
Agent marketplaces
Wallet / signer integrations
Metered data and research APIs
Teams preparing an x402 launch

04 · BOUNDARY

05 · PROOF

Existing public proof

The method comes from protocol-failure research plus BHRIGU's own bounded Base Sepolia x402 lab. Current public claims stop short of a completed end-to-end settlement proof.

08 · PROCESS

Commercial process

QUALIFY → BOUND ONE x402 PATH → EVIDENCE RECON → 3 FINDINGS → REPAIR / VERIFICATION BLUEPRINT → REPORT → PAYMENT

09 · PRIVACY / PROTECTED IP

Privacy + protected IP boundary

First contact may include public URLs, public repositories, public documentation, a problem statement, and authorized non-secret context. If private evidence becomes essential, the process stops until a separate authorized scope exists.

The report may expose observations, evidence, findings, repair blueprint, and acceptance criteria. ORION internals, private prompts/planners/evaluators/corpora, unpublished research, credentials, and patent-sensitive mechanisms remain protected.

10 · SUPPORT SEPARATION

Voluntary Bitcoin support — not payment for this service.

The existing /support corridor remains voluntary research support and does not buy access, priority, ownership, or this paid recon.

11 · START

One x402 path. Make the failure state observable before it becomes a payment incident.

Start with public evidence, the exact payment path, and the reliability decision this recon must support.
