v185-paid-service-trial is a skill for Claude Code, Codex from mayim-mayim/ln-church-agent. It costs 0 tokens per session (591 once invoked), scanned A, original, MIT.

A runbook for buying a paid external-service trial through a task system using Base-native USDC. It describes how to discover the task type, check its terms, make the purchase, and handle signed requests and payment timing.

In plain words
What is it for?
Use it for the specified paid-service-trial tasks, where a wallet pays for one external HTTPS request and may receive a reward. It is intended for agents that can use Base and sign blockchain transactions.
Why use it?
It sets checks for unknown or changed terms and limits when money is spent. It also gives rules for protecting signing keys, using claim tokens, and confirming the required blockchain timing before purchase.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

v185-paid-service-trial scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 25d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Discover explicitly with task_type=paid_service_trial.v1 and task_schema_version=ln_church.agent_task.paid_service_trial.v1. Read this immutable manifest, Definition and wire contract before Claim. This profile spends Base native USDC on one external HTTPS GET endpoint. Purchase amount is 1–10000 atomic units; approved reward is 20000 atomic units. Reward is not guaranteed. Keep signing keys locally and never send them to LN Church.

Claim using your purchase wallet as reward_address and a stable Idempotency-Key. Do not purchase on a rejected or unknown Claim. Persist the returned Claim token privately; send it only in X-LN-Task-Claim-Token. Compare the current unpaid seller requirements to the Claim's frozen terms. Unsupported, free or changed terms mean no purchase.

Read sealed Base blocks at 0, 1, 3 and 6 seconds within a 12-second total budget until the timestamp is strictly greater than purchase_block_timestamp_exclusive_min. Otherwise do not spend; abandon the unreported Claim if appropriate. Use a fresh nonce with validAfter < validBefore and validBefore = signing_now_seconds + min(300,maxTimeoutSeconds). Use only the selected x402 v2 exact EIP-3009 GET. Persist the nonsecret complete purchase identity, original validity and submission ID before dispatch. An ambiguous paid GET must never be replayed or replaced automatically.

Report before report_deadline even when no transaction hash was returned. Include exactly the closed CompletionRequest fields; omit a missing transaction_hash. Reuse the same submission and report on recovery. A same-identity locator supplement may be sent later with its own stable Idempotency-Key; it does not extend either deadline or verification budget. LN independently verifies the purchase. HTTP failure can still qualify when payment evidence matches.

Use the private status route for recovery. Accepted is not approved or paid. PENDING approved amount is null; no-award is 0; approval is 20000. Purchase and payout hashes refer to different transactions. Verification has a one-hour window from first report and twelve finite opportunities; payout follows the existing settlement rules beyond that window. Once-per-Offer applies only after approval. ALLOW_REPEAT permits another Claim after the prior execution is terminal even while payout is pending. Never infer permission to repurchase from an unavailable or inconclusive result.

The server accepts a complete witness only when all required evidence and binding reads finish and its logical acceptance time is strictly before verification_deadline. Eligible conditional persistence may finish after that deadline. If no-award expiry wins first, late evidence cannot revive the Claim; if the witness save wins first, the saved witness can finalize later, including after a lost ACK. An unknown write or elapsed deadline alone is not a final result: recover the same Submission through private status without another purchase. verified_at is saved complete-witness acceptance time, distinct from approval and payout.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
