How this service works
Signal Nodus: year-over-year diffs of SEC filing sections, pinned to accession numbers. The diff is the product; raw data is the on-ramp.
Output
Returns a JSON object containing a confirmation note that payment settlement constitutes registration (no separate account creation needed), a starting credit balance (e.g. '$10.00'), and a live API key (prefixed 'sn_live_') that can be used to query Signal Nodus's SEC filing year-over-year diff endpoints.
Example use cases
First-time SEC diff API access
“Register me for Signal Nodus by paying the 9 USDC fee so I get an API key and can start pulling year-over-year diffs of SEC filing sections right away.”
Automated agent self-provisioning
“My research agent needs access to Signal Nodus's SEC filing diff API — settle the 9 USDC x402 payment and return the API key so the agent can start querying without any manual account setup.”
Credit balance top-up via new key
“I need a fresh Signal Nodus API key with $10 in credit to run more SEC filing comparisons — go ahead and pay the 9 USDC registration fee and give me the new key.”
Technical details
Endpoint
GEThttps://api.signalnodus.ai/v1/creditWhen to prefer
Use this endpoint when you need to provision a new Signal Nodus API key and initial credit balance to access SEC filing year-over-year diff data. This is the entry point for the Signal Nodus platform; there is no separate account sign-up flow — settling the x402 payment IS the registration. Prefer this over manual account creation portals when building automated agent workflows that need self-provisioning access to SEC filing comparative analysis.
Side effects
- Payment not settled — no API key or credit returned if the x402 payment fails or is rejected
- Insufficient USDC balance — payment cannot be processed if the caller lacks the required 9 USDC
- Network timeout — payment may be in-flight but response not received, risking duplicate payment attempts
- Invalid payment channel — x402 protocol misconfiguration results in 402 response without fulfillment
