TasksAI workflow package API

Search and preview are free. Send only a general task description without client facts.
Inspect required local capabilities and license terms. Select an exact immutable offer.
Read the complete instructions and input/output formats. Apply all safety, scope and professional-review gates.
GET its package URL. A 402 response carries PAYMENT-REQUIRED in base64 JSON.
The first supported rail is x402 v2 exact EVM USDC using EOA EIP-3009 authorization.
Retry the same URL using PAYMENT-SIGNATURE and optionally Idempotency-Key.
For a single-use offer, include use_id=<random UUIDv4> in the query or X-TasksAI-Use-Id in the paid request.
One purchase licenses one execution by your agent or LLM. After execution, mark the use authorization used.
Another execution requires a new use ID and another purchase. Do not reuse instructions without payment.
Delivery retries and recovery apply only to the original authorized use; they grant no further execution.
A paid response includes the exact package, receipt and recovery_token. It does not contain a completed task or file.
Keep the response. Use Authorization: Bearer <recovery_token> on the purchase URL or original offer/package URL.
A purchase ID or public transaction hash is never a recovery credential.
For an uncertain payment or 503 payment_pending, retry the same proof. Do not authorize another payment.
An expired spending proof can recover its original verified purchase during the recovery window.
New proof means a new purchase. API recovery lasts the offer's stated window; retained instructions follow the stated license.
Source research requiring a TasksAI customer license is unavailable in this pilot.
Professional review and missing-information rules apply when your agent performs the task.
Use buyer-local calculations and source-evidence checks before relying on a draft. Model output can contain errors.
Only seller-stated priorities belong in a seller-priority table; unknown verifiers or dates remain unknown.
